Some new perspectives on moments of random matrices

Por Fabio Deelan Cunden (University College Dublin).

Abstract: The study of ‘moments’ of random matrices (expectations of traces of powers of the matrix) is a rich and interesting subject, mainly due to its connections to enumerative geometry. I will give some background on this and then describe some recent work which offers some new perspectives (and new results).

This talk is based on joint works with Antoine Dahlqvist, Francesco Mezzadri, Neil O’Connell and Nick Simm.

AOP 2019 - IV International Conference on Applications in Optics and Photonics

The world of Optics and Photonics meet in Lisbon, Portugal, from the 31th of May to the 4th of June 2019, in the Faculty of Sciences of the University of Lisbon, at the IV International Conference on Applications in Optics and Photonics, AOP 2019.

It will be the major optics conference in Portugal next year and one of the most important at world level, aiming at discuss the recent progress and to establish a view on the future of all fields of optics and photonics.

Sumário: Na última metade do século 20, o advento da Tomografia por Emissão de Positrões (PET) e da Ressonância Magnética Nuclear (RMN) revolucionaram a imagem médica in vivo.

A PET tornou-se uma valiosa ferramenta de investigação tendo migrado rapidamente para a clínica, sendo sido seguida pela RMN alguns anos depois.
