Existence and global attractivity of an almost periodic ecological model. (English) Zbl 1049.92038
Summary: The almost periodic Lotka-Volterra model with m-predators and n-preys is considered. By constructing a suitable Lyapunov function, some sufficient conditions are obtained for the existence and global attractivity of a unique positive almost periodic solution of this model. Examples show that our criteria are new, general, and easily verifiable.
