报告简介：

In their study of the truncated sums of the classical theta functions, Andrews-Merca and Guo-Zeng posed a conjecture on truncated sums of a special case of the Jacobi triple product identity which was confirmed independently by Mao and Yee. In 2016, Chan, Ho and Mao examined the truncated series arising from two consequences of the quintuple product identity. In this talk, we establish an explicit series form with nonnegative coefficients on a new truncated sum of a special cases of the Jacobi triple product identity by taking different truncated series which is stronger than the conjecture due to Andrews-Merca and Guo-Zeng. As a corollary of our results, we obtain a new truncated sums of Jacibi's identitywhich implies another conjecture given by Guo andZeng. In addition, we determine the signs of coefficientsof new truncated sums of two well-known identities derivedfrom the quintuple product identity which can be considered as the companion results of a theorem proved by Chan, Ho and Mao.
