A Growth Model in a Random Environment1 by Janko Gravner,
We consider a model of interface growth in two dimensions, given by a height function on the sites of the one-dimensional integer lattice. According to the discrete time update rule, the height above the site x increases to the height above x − 1, if the latter height is larger; otherwise the height above x increases by 1 with probability px . We assume that px are chosen independently at rando...
متن کاملTorsion units in integral group rings of Janko simple groups
Using the Luthar-Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of integral group rings of Janko simple groups. As a consequence, for the Janko groups J1, J2 and J3 we confirm Kimmerle’s conjecture on prime graphs.
متن کاملCELLULAR AUTOMATA MODELS OF RING DYNAMICS janko gravner
This paper describes three models arising from the theory of excitable media, whose primary visual feature are expanding rings of excitation. Rigorous mathematical results and experimental/computational issues are both addressed. We start with the much{studied Greenberg{ Hastings model (GHM) in which the rings are very short{lived, but they do have a transient percolation property. By contrast,...
متن کاملIntegral Group Ring of the First Janko Simple Group
We investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the simple Janko group J1. As a consequence, for this group we confirm Kimmerle’s conjecture on prime graphs.
متن کاملCodes, Designs and Graphs from the Janko Groups
We construct some codes, designs and graphs that have the first or second Janko group, J1 or J2, respectively, acting as an automorphism group. We show computationally that the full automorphism group of the design or graph in each case is J1, J2 or J̄2, the extension of J2 by its outer automorphism, and we show that for some of the codes the same is true.
