Symmetries and related loop algebra and Virasoro algebra for self-dual Yang-Mills equation. (English) Zbl 0728.35127
Summary: The self-dual Yang-Mills equation is considered, and by using the corresponding linear system and the infinitesimal version of the ‘dressing method’ infinite numbers of symmetries of the self-dual Yang- Mills equation are obtained. The set of these symmetries forms two subsets, which constitute a loop algebra and Virasoro algebra, respectively.
