O Programa de Doutorado em Matemática em Associação Ampla UFPA/UFAM convida a comunidade acadêmica a participar da palestra 

intitulada "Elliptic Problems in Smooth and Non Smooth Domains", que será ministrada no próximo dia 26/06/2018 (terça-feira), às 14:00h, no Auditório do Instituto de Ciências Exatas e Naturais (ICEN), com o Prof. Dr. Huy Hoang Nguyen, da Universidade Federal do Rio de Janeiro (IM/UFRJ).

Abstract: "We are interested here in questions related to the regularity of solutions of eliiptic problems with Dirichlet or Neumann boundary condition. For the last 20 years, lots of work has been concerned with questions when the domain is a Lipschitz domain. We give here some complements for the case of the Laplacian, the Bilaplacian and the operator div (Agrad), when A is a matrix or a function, and we extend this study to obtain other regularity results for domains having an adequate regularity. Using the duality method, we will then revisit the work of Lions-Magenes, concerning the so-called very weak solutions, when the data are less regular. Thanks to the interpolation theory, it permits us to extend the classes of solutions and then to obtain new results of regularity."
