On the Non-Existence of Certain Classes of Generalized Bent Functions

We obtain new non-existence results of generalized bent functions from Z
ⁿ
_q
to Z
_q
(called type [n, q]). The first case is a class with types, where q = 2p
^r1
₁
p
^r2
₂
. The second case contains two types [1 <; n <; 3, 2 x 31
^e
] and [1 <; n <; 5, 2 x 151
_e
].
