A framework for creating galaxy models in the geometry of the conservation group with dark matter halos and flat rotation curves
Edward Lee Green
Pandres has developed a theory which extends the geometrical structure of a real four-dimensional space-time via a field of orthonormal tetrads with an enlarged covariance group. T…
The Commuting Algebra
Edward L. Green, Sibylle Schroll
Let be a path algebra, where is a finite quiver and is a field. We study where is the two-sided ideal in generated by all differences of parallel paths…
Model of a solar system in the conservative geometry
Edward Lee Green
Pandres has shown that an enlargement of the covariance group to the group of conservative transformations leads to a richer geometry than that of general relativity. Using orthono…
Reduction techniques for the finitistic dimension
Edward L. Green, Chrysostomos Psaroudakis, Øyvind Solberg
In this paper we develop new reduction techniques for testing the finiteness of the finitistic dimension of a finite dimensional algebra over a field. Viewing the latter algebra as…
On quasi-hereditary algebras
Edward L. Green, Sibylle Schroll
Establishing whether an algebra is quasi-hereditary or not is, in general, a difficult problem. In this paper we introduce a sufficient criterion to determine whether a general fin…
Algebras and varieties
Edward L. Green, Lutz Hille, Sibylle Schroll
In this paper we introduce new affine algebraic varieties whose points correspond to associative algebras. We show that the algebras within a variety share many important homologic…
