 The \(0\)calculus on a manifold with boundary is a microlocalization of the Lie algebra of vector fields that vanish at the boundary. It has been used by Mazzeo, Melrose to study the Laplacian of a conformally compact metric. We give a complete characterization of those \(0\)pseudodifferential operators that are Fredholm between appropriate weighted Sobolev spaces, and describe \(C^{*}\)algebras that are generated by \(0\)pseudodifferential operators. An important step is understanding the socalled reduced normal operator, or, almost equivalently, the infinite dimensional irreducible representations of \(0\)pseudodifferential operators. Since the \(0\)calculus itself is not closed under holomorphic functional calculus, we construct submultiplicative Fréchet \(*\)algebras that contain and share many properties with the \(0\)calculus, and are stable under holomorphic functional calculus (\(\Psi^{*}\)algebras in the sense of Gramsch). There are relations to elliptic boundary value problems. Readership Graduate students and research mathematicians interested in analysis. Table of Contents Part 1.
