Which solutions of the third problem for the Poisson equation are bounded?

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 6, Page 501-510, 2004., 2004
This paper deals with the problem Δu = g on G and ∂u/∂n + uf = L on ∂G. Here, G ⊂ ℝm, m > 2, is a bounded domain with Lyapunov boundary, f is a bounded nonnegative function on the boundary of G, L is a bounded linear functional on W1,2(G) representable by a real measure μ on the boundary of G, and g ∈ L2(G)∩Lp(G), p > m/2.

Notes on continuity result for conformable diffusion equation on the sphere: The linear case

open access: yesDemonstratio Mathematica, 2022
In this article, we are interested in the linear conformable diffusion equation on the sphere. Our main goal is to establish some results on the continuity problem with respect to fractional order.

Coefficients of singularities of the biharmonic problem of Neumann type: case of the crack

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 5, Page 305-313, 2003., 2003
This paper concerns the biharmonic problem of Neumann type in a sector V. We give a representation of the solution u of the problem in a form of a series u = ∑α∈ECα rα ϕα, and the functions ϕα are solutions of an auxiliary problem obtained by the separation of variables.

On some nonlinear elliptic systems with coercive perturbations in RN [PDF]

open access: yes, 2003
A nonlinear elliptic system involving the p-Laplacian is considered in the whole RN: Existence of nontrivial solutions is obtained by applying critical point theory; also a regularity result is established.A nonlinear elliptic system involving the p ...

Integrodifferential equations with analytic semigroups

open access: yesInternational Journal of Stochastic Analysis, Volume 16, Issue 2, Page 177-189, 2003., 2003
In this paper we study a class of integrodifferential equations considered in an arbitrary Banach space. Using the theory of analytic semigroups we establish the existence, uniqueness, regularity and continuation of solutions to these integrodifferential equations.

On the strongly damped wave equation and the heat equation with mixed boundary conditions

open access: yesAbstract and Applied Analysis, Volume 5, Issue 3, Page 175-189, 2000., 2000
We study two one‐dimensional equations: the strongly damped wave equation and the heat equation, both with mixed boundary conditions. We prove the existence of global strong solutions and the existence of compact global attractors for these equations in two different spaces.

Weakly hyperbolic equations with time degeneracy in Sobolev spaces

open access: yesAbstract and Applied Analysis, Volume 2, Issue 3-4, Page 239-256, 1997., 1997
The theory of nonlinear weakly hyperbolic equations was developed during the last decade in an astonishing way. Today we have a good overview about assumptions which guarantee local well posedness in spaces of smooth functions (C∞, Gevrey). But the situation is completely unclear in the case of Sobolev spaces.

The Brezis–Nirenberg problem for nonlocal systems

open access: yesAdvances in Nonlinear Analysis, 2016
By means of variational methods we investigate existence, nonexistence as well as regularity of weak solutions for a system of nonlocal equations involving the fractional laplacian operator and with nonlinearity reaching the critical growth and ...

Optimality of Serrin type extension criteria to the Navier-Stokes equations

open access: yesAdvances in Nonlinear Analysis, 2021
We prove that a strong solution u to the Navier-Stokes equations on (0, T) can be extended if either u ∈ Lθ(0, T; U˙∞,1/θ,∞−α$\begin{array}{} \displaystyle \dot{U}^{-\alpha}_{\infty,1/\theta,\infty} \end{array}$) for 2/θ + α = 1, 0 < α < 1 or u ∈ L2(0, T;
