Bergman spaces of natural -manifolds.

Adv Math (N Y) 2013 Nov;247(100):103-122

Fakultät für Mathematik, Universität Wien, Vienna, Austria.

Let be a unimodular Lie group, a compact manifold with boundary, and the total space of a principal bundle [Formula: see text] so that is also a strongly pseudoconvex complex manifold. In this work, we show that if there exists a point [Formula: see text] such that [Formula: see text] is contained in the complex tangent space [Formula: see text] of at , then the Bergman space of is large. Natural examples include the gauged -complexifications of Heinzner, Huckleberry, and Kutzschebauch. Read More

Department of Mathematics, University of Miami, Coral Gables, FL, 33146, USA ; Fakultät für Mathematik, Universität Wien, 1090 Wien, Austria.

This paper presents a new approach to the dimension theory of triangulated categories by considering invariants that arise in the pretriangulated setting. Read More

The Steiner formula for Minkowski valuations.

Adv Math (N Y) 2012 Jun;230(3):978-994

University of Salzburg, Hellbrunner Strasse 34, 5020 Salzburg, Austria.

A Steiner type formula for continuous translation invariant Minkowski valuations is established. In combination with a recent result on the symmetry of rigid motion invariant homogeneous bivaluations, this new Steiner type formula is used to obtain a family of Brunn-Minkowski type inequalities for rigid motion intertwining Minkowski valuations.

The Andrews-Sellers family of partition congruences.

Adv Math (N Y) 2012 Jun;230(3):819-838

Research Institute for Symbolic Computation (RISC), Johannes Kepler University, A-4040 Linz, Austria.

In 1994, James Sellers conjectured an infinite family of Ramanujan type congruences for 2-colored Frobenius partitions introduced by George E. Andrews. These congruences arise modulo powers of 5. Read More

Cycle decompositions: From graphs to continua.

Adv Math (N Y) 2012 Jan;229(2):935-967

Technische Universität Graz, Steyrergasse 30, 8010 Graz, Austria.

We generalise a fundamental graph-theoretical fact, stating that every element of the cycle space of a graph is a sum of edge-disjoint cycles, to arbitrary continua. To achieve this we replace graph cycles by topological circles, and replace the cycle space of a graph by a new homology group for continua which is a quotient of the first singular homology group [Formula: see text]. This homology seems to be particularly apt for studying spaces with infinitely generated [Formula: see text], e. Read More

Fractal tiles associated with shift radix systems.

Adv Math (N Y) 2011 Jan;226(1):139-175

LIRMM, CNRS UMR 5506, Université Montpellier II, 161 rue Ada, 34392 Montpellier Cedex 5, France ; LIAFA, CNRS UMR 7089, Université Paris Diderot - Paris 7, Case 7014, 75205 Paris Cedex 13, France.

Shift radix systems form a collection of dynamical systems depending on a parameter which varies in the -dimensional real vector space. They generalize well-known numeration systems such as beta-expansions, expansions with respect to rational bases, and canonical number systems. Beta-numeration and canonical number systems are known to be intimately related to fractal shapes, such as the classical Rauzy fractal and the twin dragon. Read More
