标题： The Paradigm of Pseudodual Chiral Models

摘要： 这是 Phys.~Rev.~{\em D49} 5408 (1994) 的概要和扩展。 伪对偶手征模型展示了二维场论，这些理论具有无限数量的守恒定律，但同时也允许粒子产生，这与直观预期不同——这是可积模型的一个民间定理。 我们监测了伪对偶模型的对称性，包括局部对称性和非局部对称性，这些对称性可以看作是通常的手征模型对称性的变形。 我们改进了常规算法，以更有效地生成模型的非局部对称性。 此外，我们找到了将通常的手征模型与其完全等价的对偶模型连接起来的规范变换，从而区分了伪对偶理论。 显示英文摘要

摘要： This is a synopsis and extension of Phys.~Rev.~{\em D49} 5408 (1994). The Pseudodual Chiral Model illustrates 2-dimensional field theories which possess an infinite number of conservation laws but also allow particle production, at variance with naive expectations---a folk theorem of integrable models. We monitor the symmetries of the pseudodual model, both local and nonlocal, as transmutations of the symmetries of the (very different) usual Chiral Model. We refine the conventional algorithm to more efficiently produce the nonlocal symmetries of the model. We further find the Canonical transformation which connects the usual chiral model to its fully equivalent dual model, thus contradistinguishing the pseudodual theory.
