Algebraic Vector Fields on $S^{2}$ are $2$ -generated

Yiyang Jiang, Xudong Chen

We exhibit two vector fields on $S^{2}$ , which generate the entire Lie algebra of algebraic vector fields. Compositions of the flows associated with these two vector fields enable us…

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…
