Dear Sir,
I am going to graduate from Department of Mathematics in Peking University in June next year. I am very eager to enter the Graduate School of your university next fall to study applied mathematics for Ph. D. degree.
I would appreciate it very much if you would send me a graduate catalog of your university and any other necessary information, and also a set of application forms for admission. Thank you for your kind assistance.
Sincerely yours,
Xie Gang
