Minisimposio en memoria de Francisco-Javier Sayas

Durante la celebración del congreso CEDYA / CMA 2020 se organizará un minisimposio dedicado a la memoria de Francisco-Javier Sayas González (1968-2019). En las sesiones de este minisimposio se reunirán muchos de los amigos, estudiantes y colegas cercanos a Sayas, para compartir resultados propios de las áreas de investigación en las que él trabajó.

Este minisimposio ha sido organizado por Norbert Heuer (P. Universidad Católica de Chile) y Salim Meddahi (Universidad de Oviedo). Consta de seis sesiones con charlas de 20 minutos cada una y las dos charlas plenarias a cargo de Bernardo Cockburn y Salim Meddahi.

Session 2. Monday 18:00 – 20:00. Room A3.

Chair: Heuer, Norbert (P. Universidad Católica de Chile)
