DFT-based Word Normalization in Finite Supersolvable Groups
Abstract. In this paper we discuss the word normalization problem in pc presented finite supersolvable groups: given two group elements a and b in normal form the normal form of th...

Reconstructing under Group Actions
We give a bound on the reconstructibility of an action G X in terms of the reconstructibility of a the action N X, where N is a normal subgroup of G, and the reconstructibility o...

Average Spectra and Minimum Distances of Low-Density Parity-Check Codes over Abelian Groups
Ensembles of regular low-density parity-check codes over any finite Abelian group G are studied. The nonzero entries of the parity matrix are randomly chosen, independently and uni...
