- titulo: Diversity of statistical behavior in dynamical systems
abstract: For chaotic dynamical systems, it is unfeasible to compute long-term orbits precisely. Nevertheless, we may be able to describe the statistics of orbits, that is, to compute how often an orbit will visit a prescribed region of the phase space. Different orbits may or may not follow different statistics. I will explain how to measure the statistical diversity of a dynamical system. This diversity is called emergence, is independent of the traditional notions of chaos. I will begin the talk by discussing classic problems of discretization of metric spaces and measures. Then I will apply these ideas to dynamics and define two forms of emergence. I will present several examples, culminating with new dynamical systems for which emergence is as large as we could possibly hope for. This talk is based on joint work with Pierre Berger (Paris).

In this talk we will consider partitions with symmetries. We will present some results on the existence and qualitative properties of partitions of this type for the standard sphere that give rise to sign-changing solutions of the Yamabe equation with a prescribed number of nodal domains. These results are joint work with Alberto Saldaña (Universidad Nacional Autónoma de México) and Andrzej Szulkin (Stockholm Universitet).
We will also present some results for more general manifolds that were recently obtained in collaboration with Angela Pistoia (La Sapienza Università di Roma).

- titulo: Algebraic Geometry Tools in Systems Biology
abstract: I will motivate and introduce some methods and concepts of algebraic geometry that are being used in recent years to analyze standard models in molecular biology. The algebraic theory of chemical reaction systems aims to understand their dynamic behavior by taking advantage of the algebraic structure inherent in the kinetic equations, and does not need the a priori determination of the parameters, which can be theoretically or practically impossible. I will also point out some of the mathematical challenges that arise from this application.

- titulo: Measuring the complexity of countable objects
abstract: Computability theory is the sub-area of mathematical logic that studies ways to measure the complexity of objects, constructions, theorems, and mathematical proofs related to countably infinite objects. On one hand, the natural objects seem to be linearly ordered from simpler to more complex, while, on the other hand the general objects are ordered in a chaotic way. This dichotomy between natural objects and objects in general is hard to study mathematically, as we don't have a formal definition of "natural object." The objective of this talk is to introduce Martin's conjecture (open for more than 40 years) and see how it explains this dichotomy.

- titulo: Unconditional discriminant lower bounds exploiting violations of the generalized riemann hypothesis
abstract: |
In the 1970’s Andrew Odlyzko proved good lower bounds for the discriminant of a number field. He also showed that his results could be sharpened by assuming the Generalized Riemann Hypothesis. Some years later Odlyzko suggested that it might be possible to do without GRH. I shall explain Odlyzko’s ideas and sketch how for number fields of reasonably small degree (say up to degree 11 or 12) one can indeed improve the lower known bounds by exploiting hypothetical violations of GRH. This is joint work with Karim Belabas, Francisco Diaz y Diaz and Salvador Reyes, extending unpublished results of Matías Atria.

I will describe some recent results on the characterization of those polynomials that are nonnegative on a variety \(X\) in \(R^n\). In the first part of the talk I will explain why this is an interesting problem it turns out to have a wealth of applications ranging from nonconvex optimization to stochastic control. In the second part of the talk I will explain how this problem can be approached on algebraic curves and surfaces, presenting ongoing joint work with G. Blekherman (GA Tech), R. Sinn (U.

- titulo: Transfer operators and atomic decomposition
abstract: Since the groundbreaking contributions of Ruelle, the study of transfer operators has been one of the main tools to understand the ergodic theory of expanding maps, that is, discrete dynamical systems that locally expand distances. Questions on the existence of interesting invariant measures, as well the statistical properties of such dynamics system, as exponential decay of correlations and Central Limit Theorem, can be answered studying the spectral properties of the action of these operators on suitable spaces of functions. Using the method of atomic decomposition, we consider new Banach spaces of functions (that in some cases coincides with Besov spaces) that have a remarkably simple definition and allows us to obtain very general results on the quasi-compactness of the transfer operator acting in these spaces, even when the underlying phase space and expanding map are very irregular. Joint work with Alexander Arbieto (UFRJ-Brazil).

- titulo: 'Twisted honeycombs revisited: chirality in polytope-like structures'
abstract: |
In the 70´s Coxeter considered the 4-dimensional regular polytopes and used the so-called Petrie Polygons to obtain quotients of the polytopes that, while having all possible rotational symmetry, lack reflectional symmetry. He called these objects Twisted Honeycombs. Nowadays, objects with such symmetry properties are often called chiral. In this mini-course I will review Coxeter´s twisted honeycombs and explore a natural way to extend Coxeter´s work to polytope-like structures, in particular, we shall see some properties of so-called chiral skeletal polyhedra as well as of chiral abstract polytopes.

- titulo: Mating quadratic maps with the modular group.
abstract: 'Holomorphic correspondences are polynomial relations P(z,w)=0, which can be regarded as multi-valued self-maps of the Riemann sphere, this is implicit mapssending z to w. The iteration of such a multi-valued map generates a dynamical system on the Riemann sphere: dynamical system which generalises rational maps and finitely generated Kleinian groups. We consider a specific 1-(complex)parameter family of (2:2) correspondences F_a (introduced by S. Bullett and C. Penrose in 1994), which we describe dynamically. In particular, we show that for every parameter in a subset of the parameter plane called "the connectedness locus" and denoted by M_{\Gamma}, this family behaves as rational maps on a subset of the Riemann sphere and as the modular group on the complement: in other words, these correspondences are mating between the modular group and rational maps (in the family Per_1(1)). Moreover, we develop for this family of correspondences a complete dynamical theory which parallels the Douady-Hubbard theory of quadratic polynomials, and we show that M_{\Gamma} is homeomorphic to the parabolic Mandelbrot set M_1. This is joint work with S. Bullett (QMUL).'

Específicamente, discute aspectos relativos a la construcción de subjetividades generizadas al interior de este campo científico. En base al análisis de 11 grupos focales y el diálogo con diferentes académicos/as e investigadores/as adscritos al campo de la matemática se distinguen modos de concebir sus posiciones desde la extrañeza y la otredad. En todos ellos, la perspectiva de género contribuye un marco crítico para abordar la práctica de la matemática como un proceso social, es por ello que el análisis se centra en las experiencias y trayectorias de quiénes la desarrollan, al estar marcadas por las características del campo social en que se despliegan.'

- titulo: Leavitt path algebras and graph C*-algebras associated to separated graphs
abstract: |
<p>A separated graph is a pair \((E,C)\), where \(E\) is a directed graph, \(C=\bigsqcup _{v\in E^ 0} C_v\), and \(C_v\) is a partition of \(r^{-1}(v)\) (into pairwise disjoint nonempty subsets) for every vertex \(v\). In recent years, separated graphs have been used to provide combinatorial models of several structures, often related to dynamical systems. This can be understood as a generalization of the common use of usual directed graphs in symbolic dynamics. I will survey some of these developments, including the failure of Tarski's dichotomy in the setting of topological actions, the construction of a family of ample groupoids with prescribed type semigroup, and the modeling of actions on the Cantor set.</p>

<p>Let \(A\) and \(B\) be \(C^*\)-algebras, \(A\) separable and \(I\) an ideal in \(B\). We show that for any completely positive contractive linear map \(\psi\colon A\to B/I\) there is a continuous family \(\Theta_t\colon A\to B\), for \(t\in [1,\infty)\), of lifts of \(\psi\) that are asymptotically linear, asymptotically completely positive and asymptotically contractive. If \(A\) and \(B\) carry continuous actions of a second countable locally compact group \(G\) such that \(I\) is \(G\)-invariant and \(\psi\) is equivariant, then the family \(\Theta_t\) can be chosen to be asymptotically equivariant.</p>
<p>If a linear completely positive lift for \(\psi\) exists, then we can arrange that \(\Theta_t\) is linear and completely positive for all \(t\in [1,\infty)\); this yields an equivariant version of the Choi-Effros lifting theorem. In the equivariant setting, if \(A\), \(B\) and \(\psi\) are unital, the existence of asymptotically linear unital lifts are only guaranteed if \(G\) is amenable. This leads to a new characterization of amenability in terms of the existence of asymptotically equivariant unital sections for quotient maps.</p>
<p>This talk is based on joint work with Marzieh Forough and Klaus Thomsen.</p>

<p>Sin duda una de las razones más poderosas para insistir en la comunicación de las matemáticas la público general es, al menos para mí, la urgente necesidad de popularización de estas para, sobre todo, acabar con los prejuicios que, tradicionalmente, se han tenido sobre ellas y que conducen, inexorablemente, a la ansiedad de los estudiantes desde las primeras etapas de la educación. Pero, dejando a un lado esta labor del investigador para la sociedad, la divulgación de las matemáticas también pone el trabajo de los investigadores en un escaparate para investigadores de otros ámbitos y puede conducir a la colaboración interdisciplinar. En esta charla les hablaré de cómo la divulgación de la geometría me llevó, nos llevó, a descubrir una nueva forma geométrica mirando a las glándulas salivares de la mosca de la fruta.</p>
