Abstract:

With the help of a continuation theorem based on Gaines and Mawhin's coincidence degree, easily verifiable criteria are established for the global existence of positive periodic solutions of the following nonlinear discrete state dependent delays predator-prey system [GRAPHICS] where a(i), e(j), d(i) : Z -> R+ are positive omega-periodic, omega is a fixed positive integer. b(1), b(2) : Z -> R+ are omega-periodic and Sigma(omega-1)(k=0) b(i)(k) > 0. tau(i), sigma(j), rho(i) : Z x R x R -> R(i = 1, 2,..., n, j = 1, 2,..., m) are omega-periodic with respect to their first arguments, respectively. alpha(i), beta(j), gamma(i) (i = 1, 2,..., n, j = 1, 2,..., m) are positive constants.
