摘要:
Consider the generalized Abel equation x'(t) = f(t)x(m)(t) + g(t)x(n)(t), with m > n >= 2, a > 0is a constant and fand gare continuous functions. Observe that when n = 2and m = 3we have an Abel differential equation. We obtain conditions on fand gcoefficients of Abel equation that ensure the existence of a center in x = 0.
