We consider the spherical DG categoryattached to an affine algebraic group. By definition,consists of ind‐coherent sheaves on the (derived) stack of‐local systems on the 2‐sphere. The‐dimensional version of the pair of pants endowswith an‐monoidal structure. More generally, for an algebraic stackand, we consider the‐monoidal DG category, whereis the sheaf theory introduced by Arinkin and Gaitsgory. The case ofis recovered by settingand.The cobordism hypothesis associates toan‐dimensional TFT, whose value on a manifoldof dimension(possibly with boundary) is given by thetopological chiral homology. In this paper, we compute such chiral homology, obtaining the Stokes style formula ∫MdSph(Y,n)≃IndCoh0Y∂(Md×Dn+1−d)YMd∧,where the formal completion is constructed using the obvious projection. The most interesting instance of this formula is for, the original spherical category, anda Riemann surface. In this case, we obtain a monoidal equivalence, whereis the stack of‐local systems on the topological space underlyingandis a sheaf theory related to Hochschild cochains.
