An unconditionally positive and global stability preserving NSFD scheme for an epidemic model with vaccination

An unconditionally positive and global stability preserving NSFD scheme for an epidemic model with vaccination

In this paper, a NonStandard Finite Difference (NSFD) scheme is constructed, which can be used to determine numerical solutions for an epidemic model with vaccination. Here the NSFD method is employed to derive a set of difference equations for the epidemic model with vaccination. We show that diffe...
