On perturbative quantum field theory with boundary

Abstract

Boundary quantum field theory is investigated in the Lagrangian framework. Models are defined perturbatively around the Neumann boundary condition. The analyticity properties of the Green functions are analyzed: Landau equations, Cutkosky rules together with the Coleman-Norton interpretation are derived. Illustrative examples as well as argument for the equivalence with other perturbative expansions are presented.

29 pages, 19 eps and 11 pstex figures v2: some references and comments added, misprints corrected
