Some weak type inequalities and almost everywhere convergence of Vilenkin–Nörlund means

open access: yesJournal of Inequalities and Applications, 2023
We prove and discuss some new weak type ( 1 , 1 ) $(1,1 ) $ inequalities of maximal operators of Vilenkin–Nörlund means generated by monotone coefficients. Moreover, we use these results to prove a.e. convergence of such Vilenkin–Nörlund means.

Every maximally monotone operator of Fitzpatrick–Phelps type is actually of dense type [PDF]

open access: yesOptimization Letters, 2011
We show that every maximally monotone operator of Fitzpatrick-Phelps type defined on a real Banach space must be of dense type. This provides an affirmative answer to a question posed by Stephen Simons in 2001 and implies that various important notions of monotonicity coincide.

On a boundary value problem for a Boussinesq-type equation in a triangle

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2022
Earlier, we considered an initial-boundary value problem for a one-dimensional Boussinesq-type equation in a domain that is a trapezoid, in which the theorems on its unique weak solvability in Sobolev classes were established by the methods of the theory

q,h-Opial-Type Inequalities via Hahn Operators

open access: yesDiscrete Dynamics in Nature and Society, 2022
In this paper, the well-known Hölder’s inequality is proved via Hahn differential and integral operators, which is a helping tool to establish some Opial-type inequalities via Hahn’s calculus.

On Bregman-Type Distances for Convex Functions and Maximally Monotone Operators [PDF]

open access: yesSet-Valued and Variational Analysis, 2017
Given two point to set operators, one of which is maximally monotone, we introduce a new distance in their graphs. This new concept reduces to the classical Bregman distance when both operators are the gradient of a convex function. We study the properties of this new distance and establish its continuity properties.

Maximal monotone operators and nonlinear integral equations of Hammerstein type [PDF]

open access: yesBulletin of the American Mathematical Society, 1970
A nonlinear integral equation of Hammerstein type is one of the form \( u(x) + \int_{G} {K(x,\,y)f(y,\,u(y))dy} = w(x). \)

Existence of Fixed Points of Firmly Nonexpansive-Like Mappings in Banach Spaces

open access: yesFixed Point Theory and Applications, 2010
The aim of this paper is to obtain some existence theorems related to a hybrid projection method and a hybrid shrinking projection method for firmly nonexpansive-like mappings (mappings of type (P)) in a Banach space.

Examining the Hermite–Hadamard Inequalities for k-Fractional Operators Using the Green Function

open access: yesFractal and Fractional, 2023
For k-Riemann–Liouville fractional integral operators, the Hermite–Hadamard inequality is already well-known in the literature. In this regard, this paper presents the Hermite–Hadamard inequalities for k-Riemann–Liouville fractional integral operators by
