Abstract

We establish the local Langlands conjecture for small rank general spin groups GSpin4GSpin_4 and GSpin6GSpin_6 as well as their inner forms. We construct appropriate LL-packets and prove that these LL-packets satisfy the properties expected of them to the extent that the corresponding local factors are available. We are also able to determine the exact sizes of the LL-packets in many cases.

Comments

the description of the group structure of the central extension, all the sizes of L-packets for GSpin(4) and its non quasi-split F-inner forms, and their multiplicity in restriction added; exposition improved
