A Volterra equation with nonintegrable resolvent [PDF]

Proceedings of the American Mathematical Society, 1979
A counterexample, which shows that the resolvent associated with a nonnegative, nonincreasing function need not be integrable, is constructed.

Astroglial CB1 Reveal Sex‐Specific Synaptic Effects of Amphetamine

Glia, Volume 73, Issue 8, Page 1673-1691, August 2025.
Main Points Astroglial CB1 mediate long‐term depression in the NAc through purine release. Amphetamine occludes LTD in male mice by inducing the saturation of A1 receptors. Astroglial CB1 mediate behavioral amphetamine effects in males, but not in females.

Predicting solutions of the Lotka‐Volterra equation using hybrid deep network

Theoretical and Applied Mechanics Letters, 2022
Prediction of Lotka-Volterra equations has always been a complex problem due to their dynamic properties. In this paper, we present an algorithm for predicting the Lotka-Volterra equation and investigate the prediction for both the original system and ...

Solution of Nonlinear Volterra Integral Equations with Weakly Singular Kernel by Using the HOBW Method

Advances in Mathematical Physics, 2019
We present a new numerical technique to discover a new solution of Singular Nonlinear Volterra Integral Equations (SNVIE). The considered technique utilizes the Hybrid Orthonormal Bernstein and Block-Pulse functions wavelet method (HOBW) to solve the ...

Functional representation of the Volterra hierarchy

, 2004
In this paper I study the functional representation of the Volterra hierarchy (VH). Using the Miwa's shifts I rewrite the infinite set of Volterra equations as one functional equation.

Nonlocal Cooperative Behavior, Psychological Effects, and Collective Decision‐Making: An Exemplification With Predator–Prey Models

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.
ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Boundedness of solutions of matrix nonlinear volterra difference equations

Discrete Dynamics in Nature and Society, 2002
Nonlinear discrete-time Volterra equations in a Euclidean space are considered. Conditions for the boundedness of solutions are established by virtue of recent estimates for the norm of the resolvent of Volterra operators.

Solutions of a quadratic Volterra–Stieltjes integral equation in the class of functions converging at infinity

Electronic Journal of Qualitative Theory of Differential Equations, 2018
The paper deals with the study of the existence of solutions of a quadratic integral equation of Volterra–Stieltjes type. We are looking for solutions in the class of real functions continuous and bounded on the real half-axis $\mathbb{R}_+$ and ...
