Local root numbers for elliptic curves in residue characteristic 3
Shinichi Kobayashi (Nagoya)


     Root numbers for elliptic curves over number fields are signs appeared in functional equations of Hasse-Weil L-functions. They are written as the product of local signs over all places. We give a formula for local root numbers at places over 3. I will explain the formula especially when elliptic curves have reduction with wild ramification.
