PRINCIPAL DIFFERENTIAL IDEALS AND A GENERIC INVERSE DIFFERENTIAL GALOIS PROBLEM FOR GLn
ثبت نشده
چکیده
We characterize the principal differential ideals of a polynomial ring in n indeterminates with coefficients in the ring of differential polynomials in n indeterminates and derivation given by a “general” element of Lie(GLn) and use this characterization to construct a generic Picard-Vessiot extension for GLn. In the case when the differential base field has finite transcendence degree over its field of constants we provide necessary and sufficient conditions for solving the inverse differential Galois problem for this group via specialization from our generic extension.

The Differential Galois Theory of Strongly Normal Extensions
Differential Galois theory, the theory of strongly normal extensions, has unfortunately languished. This may be due to its reliance on Kolchin’s elegant, but not widely adopted, axiomatization of the theory of algebraic groups. This paper attempts to revive the theory using a differential scheme in place of those axioms. We also avoid using a universal differential field, instead relying on a c...
متن کاملLoewy Decomposition of Linear Third-Order PDE’s in the Plane
Loewy’s decomposition of a linear ordinary differential operator as the product of largest completely reducible components is generalized to partial differential operators of order three in two variables. This is made possible by considering the problem in the ring of partial differential operators where both left intersections and right divisors of left ideals are not necessarily principal. Li...
متن کاملForeword of the Guest Editors
This special issue on Differential Algebra and Differential Equations was the idea of Bob Caviness and Bruno Buchberger and originated from a special year in differential algebra that was organized by Raymond Hoobler and William Sit at The City College of New York during 1995–1996. It may interest the reader to recall the research environment under which the special year was started. As is well...
متن کاملNonstandard Methods for Bounds in Differential Polynomial Rings
Motivated by the problem of the existence of bounds on degrees and orders in checking primality of radical (partial) differential ideals, the nonstandard methods of van den Dries and Schmidt [“Bounds in the theory of polynomial rings over fields. A nonstandard approach.”, Inventionnes Mathematicae, 76:77–91, 1984] are here extended to differential polynomial rings over differential fields. Amon...
متن کاملGalois Orbits of Principal Congruence Hecke Curves
We show that the natural action of the absolute Galois group on the ideals defining principal congruence subgroups of certain nonarithmetic Fuchsian triangle groups is compatible with its action on the algebraic curves that these congruence groups uniformize.
