报告题目:Direct sum decomposition of (quadratic) algebras
报告简介:This talk introduces the direct sum decomposition of (quadratic) algebras. We first present a criterion for determining whether a (quadratic) algebra can be decomposed, along with an algorithm developed to identify the direct sum decomposition. Then we present several applications, including the characterization of the centroid of (B-)indecomposable (quadratic) algebras and the characterization of invariant metrics on B-)indecomposable current Lie algebras. Furthermore, we give a necessary and sufficient condition for the uniqueness of the direct sum decomposition up to permutations, introduce new conditions for uniqueness, and characterize the invertible centroids of certain algebras.
