Abstract
Given an ample Hausdorff groupoid , a unital commutative ring , and a discrete twist , we establish a generalised uniqueness theorem for the twisted Steinberg algebra . By applying this theorem when is effective, we establish a Cuntz-Krieger uniqueness theorem as a corollary. We also prove a generalised graded uniqueness theorem for .
