• Varieties of Invariant Subspaces Given by Littlewood-Richardson Tableaux ﻿

[OWP-2014-01] (Mathematisches Forschungsinstitut Oberwolfach, 2014-04-25)
Given partitions $\alpha, \beta, \gamma$, the short exact sequences $0 \rightarrow N_\alpha \rightarrow N_\beta \rightarrow N_\gamma \rightarrow 0$ of nilpotent linear operators of Jordan types $\alpha, \beta, \gamma$, ...
• Weak Expansiveness for Actions of Sofic Groups ﻿

[OWP-2014-05] (Mathematisches Forschungsinstitut Oberwolfach, 2014-04-25)
In this paper, we shall introduce $h$-expansiveness and asymptotical $h$-expansiveness for actions of sofic groups. By the definitions, each h-expansive action of sofic groups is asymptotically $h$-expansive. We show that ...
