We define a non-commutative version of the punctured formal neighborhood in algebraic geometry, and apply this construction to give decompositions of the (derived) stacks $\\mathbf{Coh}^-(X)$, $\\mathbf{Perf}(X)$, and $\\mathbf{Bun}_G(X)$ along a non-linear flag of sub-stacks of X. This is joint work with B. Hennion and M. Porta. Time permitting, I will also sketch an application to the construction of Hecke operators associated to a non-linear flag on a surface.<\/p>\n
