Symmetric bilinear forms and local epsilon factors of isolated singularities in positive characteristic

Daichi Takeuchi

Let $f : X \to A_{k}^{1}$ be a morphism from a smooth variety to an affine line with an isolated singular point. For such a singularity, we have two invariants. One is a non…

On continuity of local epsilon factors of $ℓ$ -adic sheaves

Daichi Takeuchi

Let $S$ be a noetherian scheme and $f : X \to S$ be a smooth morphism of relative dimension 1. For a locally constant sheaf on the complement of a divisor in $X$ at over $S$ , De…

Blow-ups and the class field theory for curves

Daichi Takeuchi

We propose another proof of the geometric class field theory for curves by considering blow-ups of symmetric products of curves.
