Abstract

In this paper, we prove the integrality conjecture for quotient stacks given by a symmetric representation of a reductive group. This result will be crucial to generalise cohomological Donaldson-Thomas theory of 2 and 3-Calabi-Yau categories to 0 and (-1) -shifted symplectic stacks respectively.
