Solving nonlinear and dynamic programming equations on extended b-metric spaces with the fixed-point technique Abstract In this article, we present an approach to solve a wide range of nonlinear equations formulated in extended b-metric spaces based on a new fixed-point theorem on these spaces. This research effort was motivated by challenges arising in solving pattern problems efficiently that can not be addressed by using standard metric spaces. Our approach relies on a no... ... hiện toàn bộ
An adaptive splitting algorithm for the sum of two generalized monotone operators and one cocoercive operatorAbstract Splitting algorithms for finding a zero of sum of operators often involve multiple steps which are referred to as forward or backward steps. Forward steps are the explicit use of the operators and backward steps involve the operators implicitly via their resolvents. In this paper, we study an adaptive splitting algorithm for finding a zero of the sum of thr... ... hiện toàn bộ

On the nonlinear Hadamard-type integro-differential equationAbstract This paper studies uniqueness of solutions for a nonlinear Hadamard-type integro-differential equation in the Banach space of absolutely continuous functions based on Babenko’s approach and Banach’s contraction principle. We also include two illustrative examples to demonstrate the use of main theorems.

String-averaging methods for best approximation to common fixed point sets of operators: the finite and infinite casesAbstract String-averaging is an algorithmic structure used when handling a family of operators in situations where the algorithm in hand requires to employ the operators in a specific order. Sequential orderings are well known, and a simultaneous order means that all operators are used simultaneously (in parallel). String-averaging allows to use strings of indices, ... ... hiện toàn bộ

Well-posedness analysis of a stationary Navier–Stokes hemivariational inequalityAbstract This paper provides a well-posedness analysis for a hemivariational inequality of the stationary Navier-Stokes equations by arguments of convex minimization and the Banach fixed point. The hemivariational inequality describes a stationary incompressible fluid flow subject to a nonslip boundary condition and a Clarke subdifferential relation between the tota... ... hiện toàn bộ

History-dependent operators and prox-regular sweeping processesAbstract We consider an abstract inclusion in a real Hilbert space, governed by an almost history-dependent operator and a time-dependent multimapping with prox-regular values. We establish the unique solvability of the inclusion under appropriate assumptions on the data. The proof is based on the arguments of monotonicity, fixed point, and prox-regularity. We then ... ... hiện toàn bộ

Stochastic approximation method using diagonal positive-definite matrices for convex optimization with fixed point constraintsAbstract This paper proposes a stochastic approximation method for solving a convex stochastic optimization problem over the fixed point set of a quasinonexpansive mapping. The proposed method is based on the existing adaptive learning rate optimization algorithms that use certain diagonal positive-definite matrices for training deep neural networks. This paper incl... ... hiện toàn bộ
