Inertial forward-backward splitting method in Banach spaces with application to compressed sensing

Prasit CholamjiakYekini Shehu — 2019

Applications of Mathematics

We propose a Halpern-type forward-backward splitting with inertial extrapolation step for finding a zero of the sum of accretive operators in Banach spaces. Strong convergence of the sequence of iterates generated by the method proposed is obtained under mild assumptions. We give some numerical results in compressed sensing to validate the theoretical analysis results. Our result is one of the few available inertial-type methods for zeros of the sum of accretive operators in Banach spaces.

Convergence results of iterative algorithms for the sum of two monotone operators in reflexive Banach spaces

Yan TangRatthaprom PromkamPrasit CholamjiakPongsakorn Sunthrayuth — 2022

Applications of Mathematics

The aim of this paper is to propose two modified forward-backward splitting algorithms for zeros of the sum of a maximal monotone operator and a Bregman inverse strongly monotone operator in reflexive Banach spaces. We prove weak and strong convergence theorems of the generated sequences by the proposed methods under some suitable conditions. We apply our results to study the variational inequality problem and the equilibrium problem. Finally, a numerical example is given to illustrate the proposed...
