Seminar on Operations Research

The next meeting of the Seminar on Operations Research will be held on October 15, 2019, at 2 p.m. in Room 403 of IMI. A talk on: Subdifferential Stability and Subdifferential Sum Rules will be delivered by Marc Lassonde Abstract. In the first part, we discuss the stability of the strong slope and of the subdifferential of a lower semicontinuous function with respect to Wijsman perturbations of the function, i.e., perturbations described via Wijsman convergence. In the second part, we show how subdifferential sum rules can be viewed as special cases of subdifferential stability results. Everybody is invited..

Seminar on Operations Research

The next meeting of the Seminar on Operations Research will be held on July 9, 2019, at 2 p.m. in Room 403 of IMI. A talk on: On complementary eigenvalue problem will be delivered by A. Iusem, Instituto de Matematika Pura e Aplicada (IMPA), Rio de Janeiro  RJ, Brazil. Abstract. We introduce the Complementary Eigenvalue Problem (EiCP), and present basic results on existence and number of solutions. We discuss next som ии  e state-of-the-art methods for its solution; namely the spectral gradient method for the symmetric case and the hybrid method (combining a semismooth Newton method with a branch and boundsearch procedure) for the nonsymmetric case. Then we consider three extensions of the problem: The Conic Complementary Eigenvalue Problem (CEiCP), the Quadratic Complementary Eigenvalue [...]
