英文摘要:
After establishing a formal theory for getting solutions of one type of high-dimensional partial differential equation, two sets of generalized symmetries of the 3D Toda theory, which arises from a particular reduction of the 4D self-dual gravity equation, are obtained concretely by a simple formula. Each set of symmetries constitutes a generalized w(infinity) algebra which contains three types of the usual w(infinity) as special cases. Some open questions are discussed.
