• #### MOSES: A Streaming Algorithm for Linear Dimensionality Reduction ﻿

[OWP-2018-12] (Mathematisches Forschungsinstitut Oberwolfach, 2018-06-26)
This paper introduces Memory-limited Online Subspace Estimation Scheme (MOSES) for both estimating the principal components of data and reducing its dimension. More specifically, consider a scenario where the data vectors ...
• #### Multiple Bernoulli series and volumes of moduli spaces of flat bundles over surfaces ﻿

[OWP-2013-04] (Mathematisches Forschungsinstitut Oberwolfach, 2013-03-14)
Using Szenes formula for multiple Bernoulli series, we explain how to compute Witten series associated to classical Lie algebras. Particular instances of these series compute volumes of moduli spaces of flat bundles over ...
• #### Multivariate Hybrid Orthogonal Functions ﻿

[OWP-2020-04] (Mathematisches Forschungsinstitut Oberwolfach, 2020-03-12)
We consider multivariate orthogonal functions satisfying hybrid orthogonality conditions with respect to a moment functional. This kind of orthogonality means that the product of functions of different parity order ...
• #### 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 ...
• #### A new counting function for the zeros of holomorphic curves ﻿

[OWP-2009-25] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-18)
Let $f_1,..., f_p$ be entire functions that do not all vanish at any point, so that $(f_1,..., f_p)$ is a holomorphic curve in $\mathbb{CP}^{p-1}$. We introduce a new and more careful notion of counting the order of the ...
• #### New representations of matroids and generalizations ﻿

[OWP-2011-18] (Mathematisches Forschungsinstitut Oberwolfach, 2011)
We extend the notion of matroid representations by matrices over fields by considering new representations of matroids by matrices over finite semirings, more precisely over the boolean and the superboolean semirings. This ...
• #### Non-Extendability of Holomorphic Functions with Bounded or Continuously Extendable Derivatives ﻿

[OWP-2017-30] (Mathematisches Forschungsinstitut Oberwolfach, 2017-10-21)
