Linear system of the volterra integral equation with a polar kernel [PDF]

open access: yes, 2012
In this study, are considered integral equation with a polar kernel. Initial value problems for hyperbolic equations with function coefficients provides integral equation with 3-D Volterra type. Existence and uniqueness theorems of the volterra integral

Solution of boundary value problems for batteries: Operator‐theoretic methods

open access: yesAIChE Journal, Volume 71, Issue 7, July 2025.
Abstract Batteries with porous electrodes of negligible ionic and electronic conduction resistance are modeled with reaction‐diffusion equations in multilayered media. The classical separation of variables becomes inapplicable to battery problems because of nonlinearities in reaction rates and constraints of imposed current. A linear operator‐theoretic

Computation of semi-analytical solutions of fuzzy nonlinear integral equations

open access: yesAdvances in Difference Equations, 2020
In this article, we use a fuzzy number in its parametric form to solve a fuzzy nonlinear integral equation of the second kind in the crisp case. The main theme of this article is to find a semi-analytical solution of fuzzy nonlinear integral equations. A

Modeling Trophic Dynamics in Lake Võrtsjärv: Energy Flow and Species Interactions

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Aligning bioenergetic, or allometric trophic network, models accurately with empirical data remains challenging. Our present study contributes to these efforts by developing a trophic network model to describe population dynamics at Lake Võrtsjärv, Estonia, with a focus on predator–prey relationships and energy considerations.

Chebyshev polynomials to Volterra-Fredholm integral equations of the first kind

open access: yesREMAT
Numerous methods have been studied and discussed for solving ill-posed Volterra integral equations and ill-posed Fredholm integral equations, but rarely for both simultaneously.

On Monotonic and Nonnegative Solutions of a Nonlinear Volterra-Stieltjes Integral Equation

open access: yesJournal of Function Spaces, 2014
We study the existence of monotonic and nonnegative solutions of a nonlinear quadratic Volterra-Stieltjes integral equation in the space of real functions being continuous on a bounded interval. The main tools used in our considerations are the technique

Inferring community assembly processes from mangrove species–area relationships

open access: yesOikos, Volume 2025, Issue 7, July 2025.
The increasing species–area relationship (SAR) is a nearly universal ecological law. But recent theory has predicted that in systems with low large‐scale diversity the law should be violated and the SAR should be nearly flat at intermediate scales, with species richness roughly constant at some value typically greater than one.
