收藏资源简介:
UMRK is a PostgreSQL database consisting of a series of eight tables: g_data: data for simple complex Lie algebras; orbit_data: data for nilpotent orbits of simple complex Lie algebras; wrep_data: data for the irreducible representations of Weyl groups of simple complex Lie algebras; ss_data: data for the root subsystems of simple complex Lie algebras; levi_data: data for the Levi subsystems of simple complex Lie algebras; psilevi_data: data for pseudo-Levi subsubsystems (corresponding to subsets of the extended simple roots); realform_data: data for the real forms simple complex Lie algebras; wcc_data : data for the conjugacy classes of Weyl groups of simple complex Lie algebras.
UMRK是一款PostgreSQL数据库,包含八张数据表:g_data用于存储复单李代数(simple complex Lie algebras)相关数据;orbit_data用于存储复单李代数幂零轨道(nilpotent orbits)相关数据;wrep_data用于存储复单李代数外尔群(Weyl groups)不可约表示(irreducible representations)相关数据;ss_data用于存储复单李代数根子系统(root subsystems)相关数据;levi_data用于存储复单李代数列维子系统(Levi subsystems)相关数据;psilevi_data用于存储伪列维子系统(pseudo-Levi subsubsystems,对应扩展单根子集)相关数据;realform_data用于存储复单李代数实形式(real forms)相关数据;wcc_data用于存储复单李代数外尔群共轭类(conjugacy classes)相关数据。
