Integrable Generators of Polynomial Vector Fields for Complex Classical Lie Groups

Yiyang Jiang, Xudong Chen

We consider in this paper complex Lie groups $SL_{n} (C)$ for $n \geq 2$ , $SO_{n} (C)$ for $n \geq 5$ , and $Sp_{2 n} (C)$ for $n \geq 1$ .…

Integrable Generators of Algebraic Vector Fields for Real Connected Semi-simple Matrix Groups

Yiyang Jiang, Xudong Chen

We show that for any real, connected, semi-simple matrix group, its Lie algebra of algebraic vector fields can be generated by three complete vector fields.

Largest $2$ -regular Subgraphs in complete $S$ -partite Graphs

Yiyang Jiang, Xudong Chen

In this paper, we focus on the class of complete $S$ -partite graphs, for $S$ an undirected graph possibly with self-loops, and address the problem of finding largest $2$ -regular su…

Tail probability of maximal displacement in critical branching Lévy process with stable branching

Haojie Hou, Yiyang Jiang, Yan-Xia Ren +1

Consider a critical branching Lévy process ${X_{t}, t \geq 0}$ with branching rate $β > 0,$ offspring distribution ${p_{k} : k \geq 0}$ and spatial motion ${ξ_{t}, Π_{x}}$ . For any $t\ge 0…
