A guide to analytic extrapolations Part I: A program for optimal extrapolation to interior points

Title of program: ANALYT Catalogue Id: AAUT_v1_0 Nature of problem In the scattering theory of elementary particles as well as in any other branch of physics in which the analyticity of some function of physical interest has been established, one is often faced with the practical question of continuing data given on parts of the cuts, in an analytic way towards some interior points of the analyticity domain, since this problem is 'ill posed' in the Hadamard sense, in order to get sensible predictions, one has to 'stabilize' the output by means, for instance, of ...
