-  - titulo: A Robuster Scott Rank
-    abstract: The Scott rank was introduced in the 60''s as a measure of complexity for algebraic structures. There are various other ways to measure the complexity of structures that give ordinals that are close to each other, but are not necessarily equal. We will introduce a new definition of Scott rank where all these different ways of measuring complexity always match, obtaining what the author believes it the correct definition of Scott Rank. We won''t assume any background in logic, and the talk will consist mostly of an introduction to these topics.
+  - 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 This is joint work with Karim Belabas, Francisco Diaz y Diaz and Salvador Reyes, extending unpublished results of Matías Atria.

+  - titulo: Characterizations of Nonnegative polynomials of some varieties 
+    abstract: |
+      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. Lepizig) and G.G. Smith (Queen's U).

-  - titulo: Weyl groupoids
-    abstract: |
-      The structure of the finite-dimensional semisimple complex Lie algebras and groups is governed by the rich combinatorial notion of root systems. Root systems had then a large number of applications in very dissimilar areas like finite groups and singularities that through them show unexpected connections. Some decades ago root systems appeared again in the study of a large class of Hopf algebras named quantum groups. In the search of understanding the role of these Hopf algebras in the general picture, it was proposed to study some objects called Nichols algebras of diagonal type. The classification of those with finite dimension was obtained by Heckenberger with a generalization of the notion of root system as the primary tool. This notion, axiomatized later by Heckenberger, Yamane and Cuntz, turned to be ubiquitous, appearing naturally in the contexts of Lie superalgebras and modular Lie algebras. The richness and beauty of these generalized root systems with their corresponding Weyl groupoids is  just starting to be unveiled. The purpose of the talk is to introduce  generalized root systems and Weyl groupoids explaining the relations with Lie algebras and superalgebras, and quantum groups.

-  - titulo: Breathers solutions and the generalized Korteweg-de Vries equation
+  - titulo: Unique Continuation for some Nonlinear Dispersive Models
     abstract: |
-      This talk is centered in the generalized Korteweg-de Vries (KdV) equation
-      (1) \(∂_tu + ∂_x^3u + ∂_xf(u)=0, x, t ∈ R\). The case \(f(u) = u^2\) corresponds to the famous KdV eq., and \(f(u) = u^3\) to the modified KdV eq. We shall review some results concerning the initial value problem associated to the equation (1). These include local and global well-posedness, existence and stability of traveling waves, and the existence and non-existence of “breathers” solutions. The aim is to understand how the non-linearity \(f(u)\) induces these results.
+      We shall study unique continuation properties (UCP) of solutions to some time evolution eq’s. We are interested in the following two questions:      
+      
+      (1) local : if \(u_1\), \(u_2\) are solutions of the eq. which agree in an open set Ω, do they agree in the whole domain?  
+      (2) asymptotic at infinity : if \(u_1\), \(u_2\) are solutions of the eq. such that at two different times \(t_1\), \(t_2\)
+      $$ ||| u_1(·, t_j ) − u_2(·, t_j )||| < \infty,\quad j = 1, 2, $$ do they are equal in the whole domain? (\(|||\ ·\ |||\) represents an appropriate "norm")
+      We shall concentrate on these questions for solutions of (i) the Kortewegde Vries eq., the Benjamin-Ono eq., (iii) the Intermediate Long Wave eq., (iv) the Camassa-Holm eq. and (v) related models. These are integrable models and the last three are non-local.
