报告题目 :A new differential operator: difficulties and perspectives
摘要: This talk is concerned with the analysis of a new differential operator, recently introduced by Charles Stuart, in relationship with concrete models arising in mathematical physics. I shall first consider the linear and sublinear cases and I shall describe various conditions that guarantee the existence of solutions for a class of nonhomogeneous elliptic equations with Dirichlet boundary condition. In the second part of this talk, I shall discuss the subcritical and critical cases. This talk is based on joint works with Louis Jeanjean and Giovany Figueiredo.
