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.

On the structure of ionizing shock waves in magnetofluiddynamics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 7, Page 395-415, 2002., 2002
Ionizing shock waves in magnetofluiddynamics occur when the coefficient of electrical conductivity is very small ahead of the shock and very large behind it. For planner motion of plasma, the structure of such shock waves are stated in terms of a system of four‐dimensional equations.

Coupled system of a fractional order differential equations with weighted initial conditions

open access: yesOpen Mathematics, 2019
Here, a coupled system of nonlinear weighted Cauchy-type problem of a diffre-integral equations of fractional order will be considered. We study the existence of at least one integrable solution of this system by using Schauder fixed point Theorem.

On the equivalence of three-dimensional differential systems

open access: yesOpen Mathematics, 2020
In this paper, firstly, we study the structural form of reflective integral for a given system. Then the sufficient conditions are obtained to ensure there exists the reflective integral with these structured form for such system.

The unique continuation property for a nonlinear equation on trees [PDF]

open access: yes, 2014
In this paper, we study the game p-Laplacian on a tree, that is, u(x) = α / 2 max y∈S(x) u(y) + min y∈S(x) u(y) + β m y∈S(x) u(y);here x is a vertex of the tree and S(x) is the set of successors of x. We study the family of the subsets of the tree that

Existence results and continuity dependence of solutions for fractional equations

open access: yes, 2020
Using two fractional-order integral inequalities we investigate the existence and uniqueness of solutions of the fractional nonlinear Volterra integral equation and the fractional nonlinear integrodifferential equation in Banach space Cξ , using an ...

Existence and uniqueness of a classical solution to a functional‐differential abstract nonlocal Cauchy problem

open access: yesInternational Journal of Stochastic Analysis, Volume 12, Issue 1, Page 91-97, 1999., 1998
The aim of this paper is to investigate the existence and uniqueness of a classical solution to a functional‐differential abstract nonlocal Cauchy problem in a general Banach space. For this purpose, a special kind of a mild solution is introduced and the Banach contraction theorem and a modified Picard method are applied.

An Extension of the Well-Posedness Concept for Fractional Differential Equations of Caputo's Type [PDF]

open access: yes, 2013
It is well known that, under standard assumptions, initial value problems for fractional ordinary differential equations involving Caputo-type derivatives are well posed in the sense that a unique solution exists and that this solution continuously ...

Well posedness for evolution inclusions

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 4, Page 537-544, 1994., 1994
We prove the existence of a continuous selection of the multivalued map φ → Φ(φ) which is the set of all mild solutions of the evolution inclusion Here F is a multivalued map, Lipschitzian with respect to x, and A is the infinitesimal generator of a C0‐semigroup.
