Topological structure of solution sets of differential inclusions: the constrained case

open access: yesAbstract and Applied Analysis, Volume 2003, Issue 6, Page 325-351, 2003., 2003
We survey and announce some current results on the existence, the viability, and the topological structure of the viable solutions of differential equations and inclusion in Banach spaces under set constraints. Some new results concerning semilinear differential inclusions with state variables constrained to the so‐called regular and strictly regular ...

Global existence and blow-up of solutions for a general class of doubly dispersive nonlocal nonlinear wave equations [PDF]

open access: yes, 2012
This study deals with the analysis of the Cauchy problem of a general class of nonlocal nonlinear equations modeling the bi-directional propagation of dispersive waves in various contexts.

Existence of extremal periodic solutions for quasilinear parabolic equations

open access: yesAbstract and Applied Analysis, Volume 2, Issue 3-4, Page 257-270, 1997., 1997
In this paper we consider a quasilinear parabolic equation in a bounded domain under periodic Dirichlet boundary conditions. Our main goal is to prove the existence of extremal solutions among all solutions lying in a sector formed by appropriately defined upper and lower solutions.

A note on truncations in fractional Sobolev spaces [PDF]

open access: yes, 2017
We study the Nemytskii operators $u\mapsto |u|$ and $u\mapsto u^{\pm}$ in fractional Sobolev spaces $H^s(\mathbb R^n)$, $s>1$.Comment: 9 ...

Stationary Points of O'Hara's Knot Energies [PDF]

open access: yes, 2012
In this article we study the regularity of stationary points of the knot energies $E^\alpha$ introduced by O'Hara in the range $\alpha \in (2,3)$.

Global Strong Solutions for a Class of Heterogeneous Catalysis Models

open access: yes, 2016
We consider a mathematical model for heterogeneous catalysis in a finite three-dimensional pore of cylinder-like geometry, with the lateral walls acting as a catalytic surface.

Quasilinear elliptic inclusions of hemivariational type: Extremality and compactness of the solution set [PDF]

open access: yes, 2003
We consider the Dirichlet boundary value problem for an elliptic inclusion governed by a quasilinear elliptic operator of Leray–Lions type and a multivalued term which is given by the difference of Clarke's generalized gradient of some locally Lipschitz ...

UNIFORMLY BOUNDED SUPERPOSITION OPERATORS IN THE SPACE OF SECOND BOUNDED VARIATION FUNCTIONS IN THE SENSE OF SHIBA [PDF]

open access: yes, 2016
In this paper we introduce the notion of "function of second bounded variation" in the sense of Shiba, and we show that if a superposition operator applies the space of all such functions on itself and it is uniformly bounded, then its generating ...

An accelerated exponential time integrator for semi-linear stochastic strongly damped wave equation with additive noise

open access: yes, 2016
This paper is concerned with the strong approximation of a semi-linear stochastic wave equation with strong damping, driven by additive noise. Based on a spatial discretization performed by a spectral Galerkin method, we introduce a kind of accelerated ...
