In this paper we present some new existence results for singular boundary value problems by Arzela-Ascoli theorem. In particular our nonlinearity may be singular in its dependent variable.

In this paper we establish the existence of single and multiple positive solutions to the following singular discrete boundary value problem {△[Ф△x(i-1))]+q1(i)f1(i,x(i),y(i))=0,i∈{1,2,…,T}△[Ф△x(...

A stochastic two-group SIR model is presented in this paper. The existence and uniqueness of its nonnegative solution is obtained, and the solution belongs to a positively invariant set. Further- more, the globally as...

In this paper, we introduce the stochasticity into an HIV-1 infection model with cytotoxic T lymphocytes (CTLs) immune response via the technique of parameter perturbation. We show that there is a positive solution ...
