Solvability of Boundary Value Problems for a Class of Third-Order Functional Difference Equations

open access: yesSarajevo Journal of Mathematics
Consider the boundary value problems consisting of the functional difference equation$$\Delta^3x(n)=f(n,x(n+2),x(n-\tau_1(n)),\dots,x(n-\tau_m(n))),\;\;n\in[0,T] $$ and the following boundary value conditions\[\begin{cases}x(0)=x(T+3)=x(1)=0,\\x(n)=\psi ...

Mathematical modelling of HIV epidemic and stability analysis

open access: yes, 2014
A nonlinear mathematical model of differential equations with piecewise constant arguments is proposed. This model is analyzed by using the theory of both differential and difference equations to show the spread of HIV in a homogeneous population ...
