【Abstract】 In this paper,we introduce the concept of Borel direction of e-type order and give asucient and necessary condition for it. As an application,we establish the connection between the e-type exponent of convergence of the zeroes and Borel direction of e-type order for the solutions of second order differential equation with transcendental entire function coeffcients.更多还原
