| Abstract | Given an algebraic stack with quasiaffine diagonal, we show that each G(m)-gerbe comes from a central separable algebra. In other words, Taylor's bigger Brauer group equals the etale cohomology in degree two with coefficients in G(m). This gives new results also for schemes. We use the method of twisted sheaves explored by Lieblich and de Jong. |
