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
(Communications in Algebra, 1997-12-01) [Artigo]
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 ...
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 ...
On the geometry of non-classical curves
(Boletim da Sociedade Brasileira de Matemática, 1992-03-01) [Artigo]
In this paper we relate the numerical invariants attached to a projective curve, called the order sequence of the curve, to the geometry of the varieties of tangent linear spaces to the curve and to the Gauss maps of the ...
Singularity theory and equivariant bifurcation problems with parameter symmetry
(Mathematical Proceedings of the Cambridge Philosophical Society, 1996-10-01) [Artigo]
(Journal of Algebra, 1996-04-15) [Artigo]
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 ...
Algebraic path formulation for equivariant bifurcation problems
(Mathematical Proceedings of the Cambridge Philosophical Society, 1998-09-01) [Artigo]
Polars of Artin-Schreier curves
