(Polytechnic University of Puerto Rico, 1994-12)
Cubic orthomodular connected lattices of height 3 and orthomodular connected projective configurations The construction of a connected orthomodular projective configuration, from a cubic, connected, orthomodular lattice ...
Hadamard matrices, strongly regular graphs, and Galois fields
(Polytechnic University of Puerto Rico, 1994-06)
In this paper the author uses the concept of circulant matrices and the superposition principle to find, from the adjacency matrices of three regular graphs of order 8 and degree 2, tire adjacency matrix, M, of a strongly ...
Configuraciones proyectivas ortomodulares y retículos cúbicos
(Polytechnic University of Puerto Rico, 1995-12)
Orthomodular projective configurations and cubic lattices The author shows the construction of a cubic, connected, orthomodular attice of height 3, from a connected, orthomodular, projective configuration and gives the ...
Inscribed r-gons: A Combinatorial approach
(Polytechnic University of Puerto Rico, 1996-12)
The author uses the concept of circular combinations to find the number of r-gons that can be inscribed in a n-gon.
Classification of nr-graphs
(Polytechnic University of Puerto Rico, 1997-06)
When all possible r-gons are inscribed in an n-gon, the resulting n-graph falls into one of the following three categories: s-regular (sr or strongly regular), //-regular, or regular (k-regular). The definitions and necessary ...
New technologies in mathematics
(Polytechnic University of Puerto Rico, 1998-06)
Throughout the ages, the development of computational instruments runs parallel to the development of mathematics playing an important role in the dissemination of this subject matter and its applications. Nevertheless, ...
