Dougall 5F4求和公式是特殊函数论中一个重要的级数求和公式,其在不同领域中的应用已被人们广泛讨论.本文以该公式为基础导出了一些新的求和公式,并利用这些公式给出了一系列新的关于1/π和1/π2的Ramanujan型级数公式.
Dougall's 5F4 summation formula plays an important role in the theory of special functions, and its various applications have been widely discussed. Using Dougall's 5F4 summation formula, we derive some new summation formulas, from which new Ramanujan type series for 1/π and 1/π2 are obtained.
