Dynamical Twists in Hopf Algebras
We establish a bijective correspondence between gauge equivalence classes of dynamical twists in a finite-dimensional Hopf algebra H based on a finite abelian group A and equivalence classes of pairs (K, {Vλ}λ∈Â), where K is an H-simple left H-comodule semisimple algebra and {Vλ}λ∈Â is a family of irreducible representations satisfying certain conditions. Our results generalize the results obta...
متن کاملOn the Hopf Algebraic Structure of Lie Group Integrators
A commutative but not cocommutative graded Hopf algebra HN , based on ordered (planar) rooted trees, is studied. This Hopf algebra is a generalization of the Hopf algebraic structure of unordered rooted trees HC , developed by Butcher in his study of Runge-Kutta methods and later rediscovered by Connes and Moscovici in the context of noncommutative geometry and by Kreimer where it is used to de...
متن کاملDYNAMICAL TWISTS IN HOPF ALGEBRAS 3 Proof
We establish a bijective correspondence between gauge equivalence classes of dynamical twists in a finite-dimensional Hopf algebra H based on a finite abelian group A and equivalence classes of pairs (K, {V λ } λ∈ b A), where K is an H-simple left H-comodule semisimple algebra and {V λ } λ∈ b A is a family of irreducible representations satisfying certain conditions. Our results generalize the ...
متن کاملAlgebraic Geometry of Hopf
We continue the investigation of Hopf-Galois extensions with central invariants started in [29]. Our objective is not to imitate algebraic geometry using Hopf-Galois extension but to understand their geometric properties. Let H be a finite-dimensional Hopf algebra over a ground field k. Our main object of study is an H-Galois extension U ⊇ O such that O is a central subalgebra of U . Let us bri...
متن کاملDeconstructing Hopf Spaces
We characterize Hopf spaces with finitely generated cohomology as algebra over the Steenrod algebra. We “deconstruct” the original space into an Hspace Y with finite mod p cohomology and a finite number of p-torsion EilenbergMac Lane spaces. One reconstructs X from Y by taking extensions by principal H-fibrations. We give a precise description of homotopy commutative H-spaces in this setting an...
