A Hybrid Semismooth Quasi-Newton Method for Structured Nonsmooth Operator Equations in Banach Spaces

We present an algorithm for the solution of structured nonsmooth operator equations in Banach spaces. Specifically, we seek roots of mappings that involve the composition of a smooth outer and a semismooth inner map. To exploit this structure we propose a hybrid approach in which the semismooth part is linearized in th...
