| contents | We introduce an $R$-sectoriality perturbation technique for non-commuting operators defined in Bochner spaces. Based on this and on bounded $H^{\infty}$-functional calculus results for the Laplacian on manifolds with conical singularities, we show maximal $L^{q}$-regularity for the Laplacian on manifolds with edge type singularities in appropriate weighted Sobolev spaces. As an application, we consider the porous medium equation on manifolds with edges and show short time existence, uniqueness and maximal regularity for the solution. We also provide space asymptotics near the singularities in terms of the local geometry. |
