• #### Milnor fibre homology via deformation ﻿

[OWP-2015-22] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
In case of one-dimensional singular locus, we use deformations in order toget refined information about the Betti numbers of the Milnor fibre.
• #### A nested family of k-total effective rewards for positional games ﻿

[OWP-2015-21] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We consider Gillette's two-person zero-sum stochastic games with perfect information. For each $k \in \mathbb{Z}_+$ we introduce an effective reward function, called $k$-total. For $k = 0$ and $1$ this function is known ...
• #### A potential reduction algorithm for two-person zero-sum mean payoff stochastic games ﻿

[OWP-2015-19] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We suggest a new algorithm for two-person zero-sum undiscounted stochastic games focusing on stationary strategies. Given a positive real $\epsilon$, let us call a stochastic game $\epsilon$-ergodic, if its values from any ...
• #### A Pseudo-Polynomial Algorithm for Mean Payoff Stochastic Games with Perfect Information and Few Random Positions ﻿

[OWP-2015-20] (Mathematisches Forschungsinstitut Oberwolfach, 2015)
We consider two-person zero-sum stochastic mean payoff games with perfect information, or BWR-games, given by a digraph $G = (V,E)$, with local rewards $r : E \to \mathbb{Z}$, and three types of positions: black $V_B$, ...
• #### Torsion-free Covers of Solvable Minimax Groups ﻿

[OWP-2015-15] (Mathematisches Forschungsinstitut Oberwolfach, 2015-11-18)
We prove that every finitely generated solvable minimax group can be realized as a quotient of a torsion-free solvable minimax group. This result has an application to the investigation of random walks on finitely generated ...
