Title: Reductions of Galois Representations: Act 1.5

Abstract: We shall describe recent progress on the question of writing
down the reductions of certain local Galois representations. We shall
focus on the case of half integral slopes (especially slope 3/2)
where the behaviour of the reduction is both more complicated and
more interesting.

Our proof uses the mod p Local Langlands Correspondence to reduce the
problem to computing the reductions of certain locally algebraic
representations of GL_2 of the p-adics on certain functions on
the underlying tree
