Standard Polynomials for Principal Subalgebras of Path Algebras
Yihao Zheng, Shenglin Zhu
We investigate standard polynomials for principal subalgebras of path algebras. First, we use standard polynomials to study the -theory of principal subalgebras. Then we descri…

Nilpotent Lie algebras obtained by ordered sets and Ricci solitons
Yihao Zheng, Shenglin Zhu
Nilpotent Lie groups with left-invariant metrics provide nontrivial examples of Ricci solitons. Some typical examples are given by the class of two-step nilpotent Lie algebras obta…
