Abstract

In this talk I will introduce our work on the spreading speed of the noncompact integer-difference models.

In this work, we gave an abstract framework of the spreading speed of the noncompact operator which has principal eigenvalue. Furthermore, we will investigate the existence of the principal eigenvalues of a class of positive integral operators which are not compact. Then we will show an application of our theory to such operators.
