Seminar on Algebra, Geometry and Physics II: In the second part we will review Orlov comparison theorem with the singularity category, the sheaf

of vanishing cycles over a dvr and present some elements of the proof that the

matrix factorization is given by vanishing cohomology. Finally we hope to put the result in perspective

of vanishing cycles over a dvr and present some elements of the proof that the

*l*-adic realization ofmatrix factorization is given by vanishing cohomology. Finally we hope to put the result in perspective

regarding Toën--Vezzosi approach to the conductor formula.
