Pseudo-differential calculus on manifolds with geometric singularities
Pseudo-differential calculus on manifolds with geometric singularities
Differential and pseudo-differential operators on a manifold with (regular) geometric singularities can be studied within a calculus, inspired by the concept of classical pseudo-differential operators on a C∞ manifold. In the singular case the operators form an algebra with a principal symbolic hierarchy σ = (σj)0≤j≤k, with k being the …
