Multivariable Dimension Polynomials and New Invariants of Differential Field Extensions
We introduce a special type of reduction in the ring of differential polynomials and develop the appropriate technique of characteristic sets that allows to generalize the classical Kolchin’s theorem on differential dimension polynomial and find new differential birational invariants of a finitely generated differential field extension. 2000 Mathematics Subject Classification. 12H05, 12H20, 13N15.
متن کاملCalculating Invariants as Coreflexive Bisimulations
Invariants, bisimulations and assertions are the main ingredients of coalgebra theory applied to computer systems engineering. In this paper we reduce the first to a particular case of the second and show how both together pave the way to a theory of coalgebras which regards invariant predicates as types. An outcome of such a theory is a calculus of invariants’ proof obligation discharge, a fra...
متن کاملHopf Galois structures on primitive purely inseparable extensions
Let L/K be a primitive purely inseparable extension of fields of characteristic p, [L : K] > p, p odd. It is well known that L/K is Hopf Galois for some Hopf algebra H, and it is suspected that L/K is Hopf Galois for numerous choices of H. We construct a family of K-Hopf algebras H for which L is an H-Galois object. For some choices of K we will exhibit an infinite number of such H. We provide ...
متن کاملExtensions of Quandles and Cocycle Knot Invariants
Quandle cocycles are constructed from extensions of quandles. The theory is parallel to that of group cohomology and group extensions. An interpretation of quandle cocycle invariants as obstructions to extending knot colorings is given, and is extended to links component-wise.
متن کاملHopf-galois Extensions with Central Invariants
We study a class of algebra extensions which usually appear in the study of restricted Lie algebras or various quantum objects at roots of unity. The present paper was inspired by the theory of nonrestricted representations of restricted Lie algebras and the theory of quantum groups at roots of unity where algebras are usually finitely generated modules over their centers. Our objective is to d...
