Nonlinear integral inequality in two independent variables [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 11, Issue 1, Page 115-119, 1988., 1986
In this note, the authors obtain a generalization of the integral inequality of Bihari [1] to a nonlinear inequality in two independent variables. With the aid of this inequality a bound for the solution of a nonlinear partial differential equation is established.

On semilinear inequalities involving the Dunkl Laplacian and an inverse-square potential outside a ball [PDF]

open access: yesAdvances in Nonlinear Analysis
Let Δk{\Delta }_{k} be the Dunkl generalized Laplacian operator associated with a root system RR of RN{{\mathbb{R}}}^{N}, N≥2N\ge 2, and a nonnegative multiplicity function kk defined on RR and invariant by the finite reflection group WW.

Fujita-type theorems for a quasilinear parabolic differential inequality with weighted nonlocal source term

open access: yesAdvances in Nonlinear Analysis, 2023
This work is concerned with the nonexistence of nontrivial nonnegative weak solutions for a quasilinear parabolic differential inequality with weighted nonlocal source term in the whole space, which involves weighted polytropic filtration operator or ...

Uniqueness in Rough Almost Complex Structures and Differential Inequalities [PDF]

open access: yes, 2009
We prove that for almost complex structures of H\"older class at least 1/2, any J-holomorphic disc, that is constant on some non empty open set, is constant. This is in striking contrast with well known, trivial, non-uniqueness results.

On the longtime behavior of a viscous Cahn-Hilliard system with convection and dynamic boundary conditions [PDF]

open access: yes, 2018
In this paper, we study the longtime asymptotic behavior of a phase separation process occurring in a three-dimensional domain containing a fluid flow of given velocity. This process is modeled by a viscous convective Cahn-Hilliard system, which consists

Global and blow-up solutions for quasilinear parabolic equations with a gradient term and nonlinear boundary flux [PDF]

open access: yes, 2014
This work is concerned with positive classical solutions for a quasilinear parabolic equation with a gradient term and nonlinear boundary flux. We find sufficient conditions for the existence of global and blow-up solutions.

SOME NONLINEAR DIFFERENTIAL INEQUALITIES AND AN APPLICATION TO HÖLDER CONTINUOUS ALMOST COMPLEX STRUCTURES [PDF]

open access: yes, 2011
. We consider some second order quasilinear partial differential inequalities for real valued functions on the unit ball and find conditions under which there is a lower bound for the supremum of nonnegative solutions that do not vanish at the origin. As

Impulsive nonlocal nonlinear parabolic differential problems

open access: yesInternational Journal of Stochastic Analysis, Volume 6, Issue 3, Page 247-260, 1993., 1993
The aim of the paper is to prove a theorem about a weak impulsive nonlinear parabolic differential inequality together with weak impulsive nonlocal nonlinear inequalities. A weak maximum principle for an impulsive nonlinear parabolic differential inequality together with weak impulsive nonlocal nonlinear inequalities and an uniqueness criterion for the

Bifurcation analysis of a predator-prey system with self- and cross-diffusion and constant harvesting rate [PDF]

open access: yes, 2014
In this paper, we focus on a ratio dependent predator-prey system with self- and cross-diffusion and constant harvesting rate. By making use of a brief stability and bifurcation analysis, we derive the symbolic conditions for Hopf, Turing and wave ...

Strong maximum principles for parabolic nonlinear problems with nonlocal inequalities together with integrals

open access: yesInternational Journal of Stochastic Analysis, Volume 3, Issue 1, Page 65-79, 1990., 1990
In [4] and [5], the author studied strong maximum principles for nonlinear parabolic problems with initial and nonlocal inequalities, respectively. Our purpose here is to extend results in [4] and [5] to strong maximum principles for nonlinear parabolic problems with nonlocal inequalities together with integrals.
