On the computation of the HNF of a module over the ring of integers of a number field
Jean-François Biasse, Claus Fieker, Tommy Hofmann
We present a variation of the modular algorithm for computing the Hermite normal form of an -module presented by Cohen, where is the ring of integers o…
Computing in quotients of rings of integers
Tommy Hofmann, Claus Fieker
We develop algorithms to turn quotients of rings of rings of integers into effective Euclidean rings by giving polynomial algorithms for all fundamental ring operations. In additio…
Zeta Functions of Lattices of the Symmetric Group
Tommy Hofmann
The symmetric group of degree admits an -dimensional irreducible -module corresponding to the hook partition …
Dimensionally Induced Phase Transition of the Weakly Interacting Ultracold Bose Gas
Bernhard Irsigler, Axel Pelster
We investigate the dimensionally induced phase transition from the normal to the Bose-Einstein-condensed phase for a weakly interacting Bose gas in an optical lattice. To this end…
Bottleneck accumulation of hybrid magneto-elastic bosons
Dmytro A. Bozhko, Peter Clausen, Gennadii A. Melkov +6
It is known that an ensemble of magnons, quanta of spin waves, can be prepared as a Bose gas of weakly interacting quasiparticles with conservation of the particle number. Furtherm…
A Generalized Approximation Framework for Fractional Network Flow and Packing Problems
Michael Holzhauser, Sven O. Krumke
We generalize the fractional packing framework of Garg and Koenemann to the case of linear fractional packing problems over polyhedral cones. More precisely, we provide approximati…
