The homology of invariant group chains
Kevin P. Knudson
If is a group acting as a group of automorphisms of another group (with finite orbits), denote by the subcomplex of -invariant chains in the bar complex $C_*(…
Low-temperature nucleation in a kinetic Ising model with soft stochastic dynamics
Kyungwha Park, Per Arne Rikvold, Gloria M. Buendia +1
We study low-temperature nucleation in kinetic Ising models by analytical and simulational methods, confirming the general result for the average metastable lifetime, <tau> = A*exp…
Projective Dynamics Analysis of Magnetization Reversal
G. Brown, M. A. Novotny, P. A. Rikvold
The computational Projective Dynamics method is used to analyze simulations of magnetization reversal in nanoscale magnetic pillars. It is shown that this method can be used to det…
Punctuated equilibria and 1/f noise in a biological coevolution model with individual-based dynamics
Per Arne Rikvold, R. K. P. Zia
We present a study by linear stability analysis and large-scale Monte Carlo simulations of a simple model of biological coevolution. Selection is provided through a reproduction pr…
The mapping class group of a disk with infinitely many holes
Paul Fabel
A left orderable completely metrizable topological group is exhibited containing Artin's braid group on infinitely many strands. The group is the mapping class group (rel boundary)…
Suppressing Roughness of Virtual Times in Parallel Discrete-Event Simulations
G. Korniss, M. A. Novotny, H. Guclu +2
In a parallel discrete-event simulation (PDES) scheme, tasks are distributed among processing elements (PEs), whose progress is controlled by a synchronization scheme. For lattice…
