New results on nonexistence of generalized bent functions

Yupeng Jiang and Yingpu Deng

Abstract: We get two kinds of new results on nonexistence of generalized bent function. The first one is Based on Feng's results by using Schmidt's field descent method. For the second kind, considering special property of the field $\mathbb{Q}(\zeta_{23^e})$, We get new nonexistence results of generalized bent functions with type $[3,2\cdot23^e]$.
