Jacobian problems in differential equations and algebraic geometry

open access: yesRocky Mountain Journal of Mathematics, 1982
One of these problems, described in §3, concerns polynomial transformations (i.e., transformations T where P and Q are polynomials in x and y) and, hence, is of interest to algebraic geometers, although they would prefer to consider transformations of C.

Completeness in partial differential algebraic geometry

open access: bronzeJournal of Algebra, 2014
Abstract This paper is part of the model theory of fields of characteristic 0, equipped with m commuting derivation operators ( DCF 0 , m ). It continues to partial differential fields work begun by Wai-Yan Pong, who treated the case m = 1 .

Differential Geometry Revisited by Biquaternion Clifford Algebra [PDF]

open access: green, 2015
In the last century, differential geometry has been expressed within various calculi: vectors, tensors, spinors, exterior differential forms and recently Clifford algebras. Clifford algebras yield an excellent representation of the rotation group and of the Lorentz group which are the cornerstones of the theory of moving frames.

Linear algebra and differential geometry on abstract Hilbert space [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2005
Isomorphisms of separable Hilbert spaces are analogous to isomorphisms of n‐dimensional vector spaces. However, while n‐dimensional spaces in applications are always realized as the Euclidean space Rn, Hilbert spaces admit various useful realizations as spaces of functions.

GEOMETRIC AND EXTENSOR ALGEBRAS AND THE DIFFERENTIAL GEOMETRY OF ARBITRARY MANIFOLDS [PDF]

open access: greenInternational Journal of Geometric Methods in Modern Physics, 2007
We give in this paper which is the third in a series of four a theory of covariant derivatives of representatives of multivector and extensor fields on an arbitrary open set U ⊂ M, based on the geometric and extensor calculus on an arbitrary smooth manifold M.
