Abstract: In this paper, we introduce an iteration scheme for viscosity approximation of zeros of accretive operators and solutions to fixed point problems in q-uniformly smooth Banach spaces with a weakly continuous duality mapping. A new… read more here.

Abstract: Low-rank approximation with zeros aims to find a matrix of fixed rank and with a fixed zero pattern that minimizes the Euclidean distance to a given data matrix. We study the critical points of this… read more here.
