Pseudo almost periodic solutions for a Lasota-Wazewska model with an oscillating death rate

In this work, we consider a new model describing the survival of red blood cells in animals. Specifically, we study a class of Lasota-Wazewska equation with pseudo almost periodic varying environment and mixed delays. By using the Banach fixed point theorem and some inequality analysis, we find sufficient conditions for the existence, uniqueness and stability of solutions. We generalize some results known for one type of delay and for the LasotaWazewska model with almost periodic and periodic coefficients. An example illustrates the proposed model.
