Stability Results for a Weakly Dissipative Viscoelastic Equation with Variable-Exponent Nonlinearity: Theory and Numerics

open access: yesMathematical and Computational Applications, 2023
In this paper, we study the long-time behavior of a weakly dissipative viscoelastic equation with variable exponent nonlinearity of the form utt+Δ2u−∫0tg(t−s)Δu(s)ds+a|ut|n(·)−2ut−Δut=0, where n(.) is a continuous function satisfying some assumptions and

Relaxations of associativity and preassociativity for variadic functions [PDF]

open access: yesFuzzy Sets and Systems, 2016
In this paper we consider two properties of variadic functions, namely associativity and preassociativity, that are pertaining to several data and language processing tasks. We propose parameterized relaxations of these properties and provide their descriptions in terms of factorization results. We also give an example where these parameterized notions

Electron transport and energy relaxation in dilute magnetic alloys [PDF]

open access: yes, 2003
We consider the effect of the RKKY interaction between magnetic impurities on the electron relaxation rates in a normal metal. The interplay between the RKKY interaction and the Kondo effect may result in a non-monotonic temperature dependence of the ...

Stretched-exponential decay functions from a self-consistent model of dielectric relaxation [PDF]

open access: yes, 2007
There are many materials whose dielectric properties are described by a stretched exponential, the so-called Kohlrausch-Williams-Watts (KWW) relaxation function.

Recent Advances in the Calculation of Dynamical Correlation Functions

open access: yesFrontiers in Physics, 2020
We review various theoretical methods that have been used in recent years to calculate dynamical correlation functions of many-body systems. Time-dependent correlation functions and their associated frequency spectral densities are the quantities of ...

Memory function for dielectric relaxation

open access: yesThe Journal of Chemical Physics, 2000
The second-order memory function (SOMF) for the dicyclohexylmetyl-2metyl succinate is obtained by using simple numerical manipulation of the experimental dielectric data. According to the prescription given in a previous paper [J. Chem. Phys. 109, 9057 (1998)], the frequency behavior of the real and imaginary parts of the SOMF is discussed in terms of ...

The Kovacs effect in the one-dimensional Ising model: a linear response analysis [PDF]

open access: yes, 2014
We analyze the so-called Kovacs effect in the one-dimensional Ising model with Glauber dynamics. We consider small enough temperature jumps, for which a linear response theory has been recently derived.
