On a modification of a discrete epidemic model. (English) Zbl 1197.39010
Summary: In this paper under some conditions on the constants ) we study the existence of positive solutions, the existence of a unique nonnegative equilibrium and the convergence of the positive solutions to the nonnegative equilibrium of the system of difference equations where and the initial values are positive numbers which satisfy the relations .
