约化群与自守李代数

Reduction Groups and Automorphic Lie Algebras

S. Lombardo, A. V. Mikhailov

摘要:

研究一类新的无穷维李代数,它在可积方程理论中有重要的应用。这些代数的构造与自守函数的构造非常相似,这激发了自守李代数的名称。对于自守李代数,我们提出的基地,他们是quasigraded和所有的结构常数可以明确地写出。这些代数在两个子代数上有一个有用的因式分解,类似于当前代数在正负部分上的因式分解。

英文摘要:

We study a new class of infinite dimensional Lie algebras, which has important applications to the theory of integrable equations. The construction of these algebras is very similar to the one for automorphic functions and this motivates the name automorphic Lie algebras. For automorphic Lie algebras we present bases in which they are quasigraded and all structure constants can be written out explicitly. These algebras have a useful factorisations on two subalgebras similar to the factorisation of the current algebra on the positive and negative parts.
