Lie theory is named after its founder, 19th century Norwegian mathematician Sophus Lie. This theory is used to describe continuous symmetries of mathematical and physical objects. Applying this theory, Einstein derived his special relativity theory from a single postulate about the symmetry structure of the space-time. In this example, the number of symmetries is infinite, but the dimension of the group of symmetries is still finite. In string theory, on the other hand, the group of symmetries is infinite-dimensional. This proposal is aimed at the advancement of the infinite-dimensional Lie theory with a view on possible applications to string theory.

Lie理论是以其创始人、世纪挪威数学家Sophus Lie命名的。这个理论被用来描述数学和物理对象的连续对称性。应用这一理论，爱因斯坦从关于时空对称结构的单一假设中推导出了他的狭义相对论。在这个例子中，对称的数量是无限的，但对称群的维数仍然是有限的。另一方面，在弦论中，对称群是无限维的。这个建议的目的是为了推进无限维李理论，以期在弦理论中有可能的应用。
