Colóquio de Matemática - Looking for poles of solutions of Painlevé equations
Por Davide Masoero (Faculdade de Ciências da Universidade de Lisboa).
Sumário: Since the early work of Gauss and Riemann on the hypergeometric function, the study of singularities of linear ordinary differential equations in the complex plane is a central topic in mathematical physics. Their efforts culminated in Hilbert's twenty-first problem, which was solved - negatively - in recent years.
