Construction and decoding of BCH codes over finite commutative rings
(Linear Algebra and Its Applications, 1999-01-01) [Artigo]
BCH codes over arbitrary finite commutative rings with identity are derived in terms of their locator vector. The derivation is based on the factorization of xs -1 over the unit ring of an appropriate extension of the ...
On n-Hilbert fields in characteristic 2

A new monohedral hexamorphic prototile
(Journal of Combinatorial Theory Series A, 1997-11-01) [Artigo]
In this paper we apply the fitting method and a result due to Martin (see [''Polynominoes-A Guide to Puzzles and Problems in Tiling,'' the Mathematical Association of American, New York, 1991] to get a hexamorphic prototile ...
Singularity theory and equivariant bifurcation problems with parameter symmetry

A RELATIVE COHOMOLOGICAL INVARIANT FOR GROUP PAIRS
(Manuscripta Mathematica, 1994-04-01) [Artigo]
We define a cohomological invariant E(G, S, M) where G is a group, S is a non empty family of (not necessarily distinct) subgroups of infinite index in G and M is a F2G-module (F2 is the field of two elements). In this ...

Exact boundary control for the wave equation in a polyhedral time-dependent domain
(Applied Mathematics Letters, 1999-05-01) [Artigo]
We establish exact boundary controllability for the wave equation in a polyhedral domain where a part of the boundary moves slowly with constant speed in a small interval of time. The control on the moving part of the ...
