The perturbiners have been constructed in Yang-Mills, in SUSY Yang-Mills, in gravity, and in sin(h)-Gordon.Contribution to the Proceedings of the XXXIVth Rencontres de Moriond, Electroweak Interactions and Unified Theories, Les Arcs, France, 13-20 Mar 1999, 4 pages, latexHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
