Multiple Solutions for Nonhomogeneous Neumann Differential Inclusion Problems by the p(x)-Laplacian

The Scientific World Journal, 2013
A class of nonlinear Neumann problems driven by p(x)-Laplacian with a nonsmooth locally Lipschitz potential (hemivariational inequality) was considered. The approach used in this paper is the variational method for locally Lipschitz functions.

On fractal properties of Weierstrass-type functions

Proceedings of the International Geometry Center, 2019
In the sequel, starting from the classical Weierstrass function defined, for any real number $x$, by $ {\mathcal W}(x)=\displaystyle \sum_{n=0}^{+\infty} \lambda^n\,\cos \left(2\, \pi\,N_b^n\,x \right)$, where $\lambda$ and $N_b$ are two real numbers ...

Deep reinforcement learning for multi‐restart metaheuristics: an environment design for a hybrid of unbiased exploratory search and covariance matrix adaptation evolution strategy

International Transactions in Operational Research, EarlyView.
Abstract Multi‐restart metaheuristics can be highly effective for complex optimization problems, yet their performance depends critically on how restarts and algorithmic parameters are selected. This paper introduces a reinforcement learning approach for managing restart‐level decisions and parameter configurations in the UES–CMA‐ES hybrid ...

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

A note on N-soliton solutions for the viscid incompressible Navier–Stokes differential equation

AIP Advances, 2022
Repetitive curling of the incompressible viscid Navier–Stokes differential equation leads to a higher-order diffusion equation. Substituting this equation into the Navier–Stokes differential equation transposes the latter into the Korteweg–De Vries ...

Too Much Finance: Mechanisms That Harm Growth and Policy Implications

The Manchester School, EarlyView.
ABSTRACT The mechanisms for the financial sector to harm growth arise through short‐termism of financial markets. This leads to the misallocation of resources in the private sector, leading to financial crises and damage to growth. However, harm to growth comes not only from financial crises, but also from the failure of short‐termist financial markets

Approximation properties of some singular integral on the classes of functions defined by the modulus of continuity

Researches in Mathematics
The paper investigates the asymptotic behavior of the exact upper bounds of deviations in the uniform metric of the Weierstrass integrals of functions belonging to the classes $W^rH_{\omega}$, generated by the modulus of continuity $\omega(t)$.

New Periodic Solutions for the Singular Hamiltonian System

Abstract and Applied Analysis, 2014
By use of the Cerami-Palais-Smale condition, we generalize the classical Weierstrass minimizing theorem to the singular case by allowing functions which attain infinity at some values. As an application, we study certain singular second-order Hamiltonian

On the Applications of the Generalized Littlewood Theorem Concerning Integrals of the Logarithm of Analytical Functions to Elliptic Functions

Axioms, 2023
Recently, we have established and used the generalized Littlewood theorem concerning contour integrals of the logarithm of analytical function to obtain new criteria equivalent to the Riemann hypothesis.
