Time dependent evolution inclusions governed by the difference of two subdifferentials

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
The purpose of this paper is to study evolution inclusions involving time dependent subdifferential operators which are non-monotone. More precisely, we study existence of solutions for the following evolution equation in a real Hilbert space $X$~: $u ...

Flow, Wind, and Stochastic Connectivity Modeling Infectious Diseases

open access: yesComplexity, 2021
We study in this paper the trends of the evolution of different infections using a SIR flow (first-order ODE system), completed by a differential inclusion, a geodesic motion in a gyroscopic field of forces, and a stochastic SIR perturbation of the flow (

Periodic homogenization and damage evolution in RVE composite material with inclusion

open access: yesFracture and Structural Integrity, 2021
This work deals with the coupling between a periodic homogenization procedure, and a damage process occurring in a Representative Volume Element (RVE) of inclusion composite materials. We mainly seek, on the one hand to determine the effective mechanical

FOURIER PROBLEM FOR WEAKLY NONLINEAR EVOLUTION INCLUSIONS WITH FUNCTIONALS

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2019
The Fourier problem or, in other words, the problem without initial conditions for evolution equations and inclusions arise in modeling different nonstationary processes in nature, that started a long time ago and initial conditions do not affect on them

Nonlinear Parabolic Variational Inequalities with Variable Time-Delay in Time Unbounded Domains

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2023
We research the well-posedness of the problem without initial condition for nonlinear parabolic variational inequalities with variable time-delay. To justify our results, we impose some assumptions on the solution behavior and growth of the data-in as ...

Effects of the Scale-dependent Vacuum Expectation Values in the Renormalization Group Analysis of Neutrino Masses [PDF]

open access: yes, 2000
The contribution of scale-dependent vacuum expectation values (VEVs) of Higgs scalars, which gives significant effects in the evolution of fundamental fermion masses in the Minimal Supersymmetric Standard Model (MSSM), is now considered in the derivation

Exact and Truncated Dynamics in Nonequilibrium Field Theory [PDF]

open access: yes, 2000
Nonperturbative dynamics of quantum fields out of equilibrium is often described by the time evolution of a hierarchy of correlation functions, using approximation methods such as Hartree, large N, and nPI-effective action techniques.

Asymptotic Giant Brach Stars as Astroparticle Laboratories [PDF]

open access: yes, 1999
We show that the inclusion of axion emission during stellar evolution introduces important changes into the evolutionary behaviour of AGB stars. The mass of the resulting C/O white dwarf is much lower than the equivalent obtained from standard evolution.
