We analyze the existence, stability, and multiplicity of T-periodic coexistence states for the classical nonautonomous periodic Lotka᎐Volterra competing species model. This is done by treating the average values of the birth rates of species as parameters, and studying the global structure of the se

Abstract
We derive necessary and sufficient conditions on a Lotka–Volterra model to admit a conservation law of Volterra's type. The result and the proof for the corresponding linear algebra problem are given in graph‐theoretical terms; they refer to the directed graph which is defined by the coefficients of the differential equation system.

We consider a Lotka᎐Volterra competition model with diffusion on R which describes the dynamics of the population of two competing species, and study the stability of positive stationary solutions of the model relative to the space X of bounded uniformly continuous functions with the supremum norm.
## Abstract In the paper we consider three classes of models describing carcinogenesis mutations. Every considered model is described by the system of (__n__+1) equations, and in each class three models are studied: the first is expressed as a system of ordinary differential equations (ODEs), the s
