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. + abstract: The Scott rank was introduced in the 60''s as a measure of complexity for algebraic structures.

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 This is joint work with Karim Belabas, Francisco Diaz y Diaz and Salvador Reyes, extending unpublished results of Matías Atria. pdf: '' speaker: nombre: Eduardo Friedman afiliacion: Universidad de Chile web: http://www.uchile.cl/portafolio-academico/impresion.jsf?username=friedman + - titulo: TBA + abstract: '' + pdf: '' + speaker: + nombre: Luz Roncal + afiliacion: UBCAM -Basque Center for applied mathematics + web: https://sites.google.com/view/luzroncal - titulo: TBA abstract: '' pdf: ''
