• #### Random dynamics of transcendental functions ﻿

[OWP-2014-12] (Mathematisches Forschungsinstitut Oberwolfach, 2014-08-20)
This work concerns random dynamics of hyperbolic entire and meromorphic functions of finite order and whose derivative satisfies some growth condition at infinity. This class contains most of the classical families of ...
• #### Spectral triples and finite summability on Cuntz-Krieger algebras ﻿

[OWP-2014-03] (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
We produce a variety of odd bounded Fredholm modules and odd spectral triples on Cuntz-Krieger algebras by means of realizing these algebras as "the algebra of functions on a non-commutative space" coming from a sub shift ...
• #### Spherical Actions on Flag Varieties ﻿

[OWP-2014-04] (Mathematisches Forschungsinstitut Oberwolfach, 2014-04-25)
For every finite-dimensional vector space $V$ and every $V$ -flag variety $X$ we list all connected reductive subgroups in $GL(V)$ acting spherically on $X$.
• #### Square wave periodic solutions of a differential delay equation ﻿

[OWP-2014-09] (Mathematisches Forschungsinstitut Oberwolfach, 2014-05-13)
We prove the existence of periodic solutions of the differential delay equation $\varepsilon\dot{x}(t) + x(t)= f(x(t-1)), \varepsilon>0$ under the assumptions that the continuous nonlinearity $f(x)$ satisfies the negative ...
• #### 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 ...
