| Research Abstract |
We get the following result in this term.
(1) Calculation of ε-factor for GL_1(F) × GL_1' (F)
We calculates the ε -factor of the representations of GL_1(F) × GL_{1'}(F) where 1 and 1' are distinct primes under some assumption. For the case GL_2(F) × GL_3(F), we need no assumption. It uses the local Langlands correspondence and non-Galois base change lift.
(2) Character formula for the supercuspidal representations of GL_1
We give a character formula for the irreducible supercuspidal representation of GL_1(F) for F a local field of the residual characteristic p ≠ 1.
