• #### The Nagata automorphism is shifted linearizable ﻿

[OWP-2008-09] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-13)
A polynomial automorphism $F$ is called shifted linearizable if there exists a linear map $L$ such that $LF$ is linearizable. We prove that the Nagata automorphism $N:= (X-Y\Delta-Z\Delta^2,Y+Z\Delta,Z)$ where $\Delta=XZ+Y^2$ ...
• #### Near critical density irregular sampling in bernstein spaces ﻿

[OWP-2013-16] (Mathematisches Forschungsinstitut Oberwolfach, 2013-07-23)
We obtain sharp estimates for the sampling constants in Bernstein spaces when the density of the sampling set is near the critical value.
• #### 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 ...
