On the existence of positive solutions of a class of parabolic reaction diffusion systems [PDF]
In this paper, we show the existence of continuous positive solutions of a class of nonlinear parabolic reaction diffusion systems with initial conditions using techniques of functional analysis and potential analysis. Mathematics Subject Classification (

Theoretical and numerical considerations on Bratu-type problems [PDF]
In this paper we present an heuristic introduction to Bratu problem and we give some variants of Bratu\u27s theorem (G. Bratu, Sur les equations integrales non lineaires, Bulletin Soc. Math. France, 42(1914), 113-142).

Third-order differential equations with three-point boundary conditions
In this paper, a third-order ordinary differential equation coupled to three-point boundary conditions is considered. The related Green’s function changes its sign on the square of definition. Despite this, we are able to deduce the existence of positive

In this article, we focus on the existence of positive solutions and establish a corresponding iterative scheme for a nonlinear fourth-order equation with indefinite weight and Neumann boundary conditions y(4)(x)+(k1+k2)y″(x)+k1k2y(x)=λh(x)f(y(x)),x∈[0,1]

Fractal-Fractional Mathematical Model Addressing the Situation of Corona Virus in Pakistan
This work is the consideration of a fractal fractional mathematical model on the transmission and control of corona virus (COVID-19), in which the total population of an infected area is divided into susceptible, infected and recovered classes.

Solvability of infinite systems of second-order differential equations with boundary conditions in ℓp [PDF]
In this paper, governed by the fundamental solutions we introduce the Green's function of the second-order differential equations in general form with respect to boundary conditions and deal with the solvability of the innite system of second-order ...

Relativistic wave equations with fractional derivatives and pseudodifferential operators
We study the class of the free relativistic covariant equations generated by the fractional powers of the d′Alembertian operator (□1/n). The equations corresponding to n = 1 and 2 (Klein‐Gordon and Dirac equations) are local in their nature, but the multicomponent equations for arbitrary n > 2 are nonlocal. We show the representation of the generalized

Homoclinic solutions for linear and linearizable ordinary differential equations
Using functional arguments, some existence results for the infinite boundary value problem x˙=F(t,x),x(−∞)=x(+∞) are given. A solution of this problem is frequently called, from Poincaré, homoclinic.
