On a class of nonclassical hyperbolic equations with nonlocal conditions

open access: yesInternational Journal of Stochastic Analysis, Volume 15, Issue 2, Page 125-140, 2002., 2002
This paper proves the existence, uniqueness and continuous dependence of a solution of a class of nonclassical hyperbolic equations with nonlocal boundary and initial conditions. Results are obtained by using a functional analysis method based on an a priori estimate and on the density of the range of the linear operator corresponding to the abstract ...

Boundedness of Solutions to a Parabolic-Elliptic Keller–Segel Equation in ℝ2 with Critical Mass

open access: yesAdvanced Nonlinear Studies, 2018
We consider the Cauchy problem for a parabolic-elliptic system in ℝ2{\mathbb{R}^{2}}, called the parabolic-elliptic Keller–Segel equation, which appears in various fields in biology and physics.

On three‐point boundary value problem with a weighted integral condition for a class of singular parabolic equations

open access: yesAbstract and Applied Analysis, Volume 7, Issue 10, Page 517-530, 2002., 2002
We deal with a three point boundary value problem for a class of singular parabolic equations with a weighted integral condition in place of one of standard boundary conditions. We will first establish an a priori estimate in weighted spaces. Then, we prove the existence, uniqueness, and continuous dependence of a strong solution.

Mixed problem with nonlocal boundary conditions for a third‐order partial differential equation of mixed type

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 7, Page 417-426, 2001., 2001
We study a mixed problem with integral boundary conditions for a third‐order partial differential equation of mixed type. We prove the existence and uniqueness of the solution. The proof is based on two‐sided a priori estimates and on the density of the range of the operator generated by the considered problem.

Quasilinear parabolic equations with p(x)-Laplacian diffusion terms and nonlocal boundary conditions

open access: yes, 2019
In this study, we prove the existence of local solution for a quasi linear generalized parabolic equation with nonlocal boundary conditions for an elliptic operator involving the variable-exponent nonlinearities, using Faedo-Galerkin arguments and ...

Spatial decay estimates for a class of nonlinear damped hyperbolic equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 1, Page 17-26, 2001., 2001
This paper is concerned with investigating the spatial decay estimates for a class of nonlinear damped hyperbolic equations. In addition, we compare the solutions of two‐dimensional wave equations with different damped coefficients and establish an explicit inequality which displays continuous dependence on this coefficient.

Existence of positive singular solutions for a class of quasilinear elliptic equations

open access: yes, 2000
We establish existence of singular positive radial solutions to-div(A(\del u\)del u) = f(u)either to a Dirichlet problem in a punctured ball centered at the origin, or in R-N\{0}. (C) 2000 Elsevier Science B.V. All rights reserved.

Best possible estimates of weak solutions of boundary value problems for quasi-linear elliptic equations in unbounded domains

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
We investigate the behaviour of weak solutions of boundary value problems for quasi-linear elliptic divergence second order equations in unbounded domains. We show the boundedness of weak solutions to our problem.
