Varieties of Invariant Subspaces Given by Littlewood-Richardson Tableaux

[OWP-2014-01] Kosakowska, Justyna; Schmidmeier, Markus (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] Chung, Nhan-Phu; Zhang, Guohua (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 ...
