Abstract

We study the existence of wave operators, in terms of limiting absorption principles for a class positively perturbed positive (semi)groups on Banach lattices. This work is a partial extension of theL1scattering theory by M. Mokhtar-Kharroubi (J. Funct. Anal.115, 1993, 119–145). An application to perturbed heat semigroups is given.
