Compressed word problems in HNN-extensions and amalgamated products
Niko Haubold, Markus Lohrey
It is shown that the compressed word problem for an HNN-extension with base group H and finite associated subgroups is polynomial time Turing-reducible to the compressed word probl…
Automatic structures of bounded degree revisited
Dietrich Kuske, Markus Lohrey
The first-order theory of a string automatic structure is known to be decidable, but there are examples of string automatic structures with nonelementary first-order theories. We p…
A unit-cell approach to the nonlinear rheology of biopolymer solutions
Pablo Fernandez, Steffen Grosser, Klaus Kroy
We propose a nonlinear extension of the standard tube model for semidilute solutions of freely-sliding semiflexible polymers. Non-affine filament deformations at the entanglement s…
Boundary field induced first-order transition in the 2D Ising model: numerical study
Elmar Bittner, Wolfhard Janke
In a recent paper, Clusel and Fortin [J. Phys. A.: Math. Gen. 39 (2006) 995] presented an analytical study of a first-order transition induced by an inhomogeneous boundary magnetic…
Make life simple: unleash the full power of the parallel tempering algorithm
Elmar Bittner, Andreas Nussbaumer, Wolfhard Janke
We introduce a new update scheme to systematically improve the efficiency of parallel tempering simulations. We show that by adapting the number of sweeps between replica exchanges…
Hypercontact structures and Floer homology
Sonja Hohloch, Gregor Noetzel, Dietmar Salamon
We introduce a new Floer theory associated to a pair consisting of a Cartan hypercontact 3-manifold M and a hyperkaehler manifold X.
