Grothendieck's Quot-scheme is a fundamental object in moduli problems. In this talk, I will introduce a degeneration of Quot-scheme with nice geometric properties. As an application, it gives a degeneration formula of Donaldson-Thomas invariants of projective threefolds. This is joint work with Jun Li.
