By using Gaines and Mawhin’s continuation theorem of coincidence degree theory and constructing Lyapunov functionals,a set of easily verifiable sufficient conditions are derived for the existence and global attractiv...
This paper analyzes permanence, existence and global attractivity of positiveperiodic solution in nonautonomous delay diffusive Lotka-Volterra competitive system fora patchstyle environment, by applying the invariant ...
We establish sufficient conditions for the existence and global attractivity of the nonnegativeperiodic solution of an integro-differential equation which can be taken as a generalization of amodel in describing the d...
