Local root numbers for elliptic curves in residue characteristic 3
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.
