Title: A spectral approach to singularity theory

Abstract: In a joint work in progress with Fuijun Fan, motivated by LG mirror symmetry theory in physics, we study a modified d-bar operator over complete Kahler manifolds. We study its spectral properties and establish a corresponding index theorem. We construct new torsion type invariants and point out possible applications to singularity theory.
