Abstract

Action Lie groupoids are used to model spaces of orbits of actions of Lie groups on manifolds. For each such action groupoid MHM\rtimes H we construct a locally convex bialgebroid Dirac(MH)\mathord{\mathrm{Dirac}}(M\rtimes H) with an antipode over Cc(M)\mathord{\mathcal{C}^{\infty}_{c}}(M), from which the groupoid MHM\rtimes H can be reconstructed as its spectral action Lie groupoid AGsp(Dirac(MH))\mathord{\mathcal{AG}_{\mathit{sp}}}(\mathord{\mathrm{Dirac}}(M\rtimes H)).
