Tilting and Refined Donaldson-Thomas Invariants
Published 25 Mar 2013 in math.RT and hep-th | (1303.6014v2)
Abstract: We study tilting for the heart A of the canonical t-structure of the finite-dimensional derived category of the Ginzburg algebra for a quiver with potential (Q,W). We give conditions on that the stable objects for a central charge on A define a sequence of simple tilts from A to A[-1]. On that conditions the refined Donaldson-Thomas invariant associated to (Q,W) is independent of the chosen central charge.
