Energy balance for fractional anti-Zener and Zener models in terms of relaxation modulus and creep compliance
Slađan Jelić, Dušan Zorica
Relaxation modulus and creep compliance corresponding to fractional anti-Zener and Zener models are calculated and restrictions on model parameters narrowing thermodynamical constr…
Generalised solutions to linear and non-linear Schrödinger-type equations with point defect: Colombeau and non-Colombeau regimes
N. Dugandžija, A. Michelangeli, I. Vojnović
For a semi-linear Schrödinger equation of Hartree type in three spatial dimensions, various approximations of singular, point-like perturbations are considered, in the form of pote…
Distributed-order time-fractional wave equations
Frederik Broucke, Ljubica Oparnica
Distributed-order time-fractional wave equations appear in the modeling of wave propagation in viscoelastic media. The material characteristics of the medium are modeled through co…
Some remarks on analytic pseudodifferential operators
Nenad Teofanov
We report some recent results on analytic pseudodifferential operators, also known as Wick operators. An important tool in our study is the Bargmann transform which provides a coup…
Stochastic parabolic equations with singular potentials
Snežana Gordić, Tijana Levajković, Ljubica Oparnica
In this work we consider a class of stochastic parabolic equations with singular space depending potential, random driving force and random initial condition. For the analysis of t…
Stepanov pseudo almost periodic functions and applications
K. Khalil, M. Kostić, M. Pinto
In this work, we present basic results and applications of Stepanov pseudo almost periodic functions with measures. Using only the continuity assumption, we prove a new composition…
Well-posedness of the fractional Zener wave equation for heterogenous viscoelastic materials
Ljubica Oparnica, Endre Süli
We explore the well-posedness of the fractional version of Zener's wave equation for viscoelastic solids, which is based on a constitutive law relating the stress tensor $\boldsymb…
On the characterisations of wave front sets via the short-time Fourier transform
Stevan Pilipovic, Bojan Prangoski
It is well known that the classical and Sobolev wave fronts were extended into non-equivalent global versions by the use of the short-time Fourier transform. In this very short pap…
Infinite order DOs: Composition with entire functions, new Shubin-Sobolev spaces, and index theorem
Stevan Pilipović, Bojan Prangoski, Jasson Vindas
We study global regularity and spectral properties of power series of the Weyl quantisation , where is a classical elliptic Shubin polynomial. For a suitable entire…
Propagation of stretched exponential moments for the Kac equation and Boltzmann equation with Maxwell molecules
Milana Pavić-Čolić, Maja Tasković
We study the spatially homogeneous Boltzmann equation for Maxwell molecules, and its -dimensional model, the Kac equation. We prove propagation in time of stretched exponential…
Solvability and microlocal analysis of the fractional Eringen wave equation
Günther Hörmann, Ljubica Oparnica, Dušan Zorica
We discuss unique existence and microlocal regularity properties of Sobolev space solutions to the fractional Eringen wave equation, initially given in the form of a system of equa…
Wave equation for generalized Zener model containing complex order fractional derivatives
Teodor M. Atanacković, Marko Janev, Sanja Konjik +1
We study waves in a viscoelastic rod whose constitutive equation is of generalized Zener type that contains fractional derivatives of complex order. The restrictions following from…
Wave fronts via Fourier series coefficients
Snjezana Maksimovic, Stevan Pilipovic, Petar Sokoloski +1
Motivated by the product of periodic distributions, we give a new description of the wave front and the Sobolev-type wave front of a distribution i…
Generalized solutions for the Euler-Bernoulli model with Zener viscoelastic foundations and distributional forces
Günther Hörmann, Sanja Konjik, Ljubica Oparnica
We study the initial-boundary value problem for an Euler-Bernoulli beam model with discontinuous bending stiffness laying on a viscoelastic foundation and subjected to an axial for…
Waves in fractional Zener type viscoelastic media
Sanja Konjik, Ljubica Oparnica, Dušan Zorica
Classical wave equation is generalized for the case of viscoelastic materials obeying fractional Zener model instead of Hooke's law. Cauchy problem for such an equation is studied:…
Singular shock waves in interactions
Marko Nedeljkov
n a number of papers it was shown that there are one-dimensional systems such that they contain solutions with, so called, overcompressive singular shock waves besides the usual el…
