报告题目：BILATERAL BAILEY LEMMA AND ROGERS-RAMANUJAN IDENTITIES
报告人：初文昌教授
报告时间：12月12日（周五）上午9：30至11：00
报告地点：数学楼报告厅102
报告摘要：We prove a bilateral Bailey Lemma and establish twenty five transformation formulae between unilateral and bilateral summations for nonterminating basic hypergeometric series. Then they are employed to show numerous identities of Rogers-Ramanujan type, including most of Slater's collection of 130 identities.

报告题目：FINITE DIFFERENCES AND DETERMINANT IDENTITIES
报告人：初文昌教授
报告时间：12月12日（周五）下午1：00至 2：00
报告地点：数学楼报告厅102
报告摘要：Determinants of higher derivatives of composite functions are evaluatedas limits of the corresponding ones concerning finite differences. As examples, several interesting identities of Wronskian and Hankel determinants are consequently derived.
