Sharp median testing and sparse criteria for generalized \(BMO\) spaces

Saeed Hashemi Sababe

We study generalized \(BMO\)-type spaces associated with a normalized family of local quasi-Banach function spaces \(\mathbb X=\{X_Q\}_{Q\subset\mathbb R^n}\). For such a family we…

Arens Products and Asymptotic Structures on Chébli-Trimèche Hypergroups under Low Regularity Conditions

Saeed Hashemi Sababe

We investigate the Arens products on the second duals of convolution algebras associated with Chébli--Trimèche hypergroups, particularly focusing on the left and right topologica…

On Kernels and Covariance Structures in Hilbert Space Gaussian Processes

Saeed Hashemi Sababe

Motivated by practical applications, I present a novel and comprehensive framework for operator-valued positive definite kernels. This framework is applied to both operator theory…

Stochastic Krasnosel skii-Mann Iterations in Banach Spaces with Bregman Distances

Saeed Hashemi Sababe, Ehsan Lotfali Ghasab

We propose a generalization of the stochastic Krasnoselskil-Mann algorithm to reflexive Banach spaces endowed with Bregman distances. Under standard martingale-difference n…

Generalized Bregman Projection Algorithms for Solving Nonlinear Split Feasibility Problems in Infinite-Dimensional Spaces

Saeed Hashemi Sababe, Ehsan Lotfali Ghasab

This paper introduces generalized Bregman projection algorithms for solving nonlinear split feasibility problems (SF P s) in infinitedimensional Hilbert spaces. The methods integra…

Iterative Splitting Methods for Stochastic Dynamic SVIs

Saeed Hashemi Sababe, Ehsan Lotfali Ghasab

This paper extends split variational inclusion problems to dynamic, stochastic, and multi-agent systems in Banach spaces. We propose novel iterative algorithms to handle stochastic…
