Asymptotic Behaviour of the QED Perturbation Series

Advances in High Energy Physics, 2017
I will summarize the present state of a long-term effort to obtain information on the large-order asymptotic behaviour of the QED perturbation series through the effective action. Starting with the constant-field case, I will discuss the Euler-Heisenberg

Computational Study on the Dynamics of a Consumer-Resource Model: The Influence of the Growth Law in the Resource

Mathematics, 2021
The dynamics of a specific consumer-resource model for Daphnia magna is studied from a numerical point of view. In this study, Malthusian, chemostatic, and Gompertz growth laws for the evolution of the resource population are considered, and the ...

The Schröder equation and asymptotic properties of linear delay differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2004
We study the asymptotic behaviour of solutions of the differential equation $$ \dot{x}(t)=-p(t)[x(t)-kx(t-\tau (t))]+q(t),\qquad t\in I=[t_0,\infty), $$ where $k\ne 0$ is a scalar, $p$ is a positive function and $\tau$ is a positive and unbounded delay ...

Permanence for a class of non-autonomous delay differential systems

Electronic Journal of Qualitative Theory of Differential Equations, 2018
We are concerned with a class of $n$-dimensional non-autonomous delay differential equations obtained by adding a non-monotone delayed perturbation to a linear homogeneous cooperative system of delay differential equations.

On Caputo–Katugampola Fractional Stochastic Differential Equation

Mathematics, 2022
We consider the following stochastic fractional differential equation CD0+α,ρφ(t)=κϑ(t,φ(t))w˙(t), 00 represents the noise level. The main result of the paper focuses on the energy growth bound and the asymptotic behaviour of the random solution ...

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Characterization for Rectifiable and Nonrectifiable Attractivity of Nonautonomous Systems of Linear Differential Equations

International Journal of Differential Equations, 2013
We study a new kind of asymptotic behaviour near for the nonautonomous system of two linear differential equations: , , where the matrix-valued function has a kind of singularity at .

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Asymptotic Behaviour of Solutions of n-th Order Ordinary Differential Equations with Regularly Varying Nonlinearities .

Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
In the paper the question of existence and asymptotic behaviour of P k +∞(λ0)–solutions, k ∈ {3, . . . , n} and λ0 ∈ {1, ±∞}, of a binomial non-autonomous n-th order ordinary differential equation with regularly varying nonlinearities was investigated ...
