Title: Complementarity problems with respect to Loewnerian cones
Speaker: David Sossa, Universidad Técnica Federico Santa María, Valparaíso, Chile

Abstract:
This work deals with the analysis and numerical resolution of a broad class of complementarity problems on spaces of symmetric matrices. The complementarity conditions are expressed in terms of the Loewner ordering or, more generally, with respect to a dual pair of Loewnerian cones. We also present a numerical method for the problem of finding the nearest Euclidean distance matrix.
