摘要
By means of Mawhin's continuation thorem, a class of p-Laplacian type differential equation with a deviating argument of the form (phi p(x'(t)))' + F(x(t))x'(t) + beta(t)g(t, x(t -tau(t, |x|(infinity)))) = e(t) is studied. A new result, related to beta(t) and the deviating argument tau(t,|x|(infinity)), is obtained. It is significant that the growth degree with respect to the variable x in g(t,x) is allowed to be greater than p - 1, which could be achieved infrequently in previous papers. (C) 2007 Elsevier Ltd.
