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. (C) 2004 Elsevier B.V. All rights reserved.
