Explicit bounds of unknown function of some new weakly singular retarded integral inequalities for discontinuous functions and their applications

open access: yesJournal of Inequalities and Applications, 2017
The purpose of the present paper is to establish some new retarded weakly singular integral inequalities of Gronwall-Bellman type for discontinuous functions, which generalize some known weakly singular and impulsive integral inequalities.

On Weak Super Ricci Flow through Neckpinch

open access: yesAnalysis and Geometry in Metric Spaces, 2021
In this article, we study the Ricci flow neckpinch in the context of metric measure spaces. We introduce the notion of a Ricci flow metric measure spacetime and of a weak (refined) super Ricci flow associated to convex cost functions (cost functions ...

Interpolation method for solving Volterra integral equations with weakly singular kernel using an advanced barycentric Lagrange formula

open access: yesAin Shams Engineering Journal, 2022
We presented an interpolation method for solving weakly singular Volterra integral equations of the second kind (SVK2). The method based on the barycentric Lagrange interpolation.. For the chosen nodes of the two singular kernel variables, we created two

Harmonic functions for singular quadrant walks

open access: yes, 2023
International audienceWe consider discrete (time and space) random walks confined to the quarter plane, with jumps only in directions (i, j) with i + j 0 and small negative jumps, i.e., i, j −1.

Positive Solutions for a Semipositone Singular ψ–Riemann–Liouville Fractional Boundary Value Problem

open access: yesMathematics
We explore the existence of positive solutions to a ψ–Riemann–Liouville fractional differential equation with a parameter and a sign-changing singular nonlinearity, supplemented with nonlocal boundary conditions which contain Riemann–Stieltjes integrals ...

SINGULAR SOLUTIONS OF CLAIRAUT-TYPE EQUATIONS IN PARTIAL DERIVATIVES WITH REVERSE TRIGONOMETRIC FUNCTIONS

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2020
Background. The problem of evaluation of the special (singular) solutions of Clairaut-type partial differential equations attracts a lot of interest studying various transformations of nonlinear equations of mathematical physics, for example, Legendre

Singularities of a class of meromorphic functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
Estimates are obtained for the number of singular points, which are not poles, lying on the unit circle of the complex plane of a class of meromorphic functions which are represented by C -fractions.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
