摘要：
In this paper we deal with the center problem for the trigonometric Abel equation d rho/d theta = a(1)(theta)rho(2) a(2)(theta)rho(3), where a1(theta) and a(2)(theta) are trigonometric polynomials in theta. This problem is closely connected with the classical Poincare center problem for planar polynomial vector fields.
