On Graded Bialgebra Deformations

چکیده
We introduce the graded bialgebra deformations, which explains Andruskiewitsch-Schneider’s liftings method. We also relate this graded bialgebra deformation with the corresponding graded bialgebra cohomology groups, which is the graded version of the one due to Gerstenhaber-Schack.

Bialgebra Cohomology, Pointed Hopf Algebras, and Deformations
We give explicit formulas for maps in a long exact sequence connecting bialgebra cohomology to Hochschild cohomology. We give a sufficient condition for the connecting homomorphism to be surjective. We apply these results to compute all bialgebra two-cocycles of certain Radford biproducts (bosonizations). These two-cocycles are precisely those associated to the finite dimensional pointed Hopf a...
متن کاملHigher Homotopy Hopf Algebras Found: a 10 Year Retrospective
The search for “higher homotopy Hopf algebras” (known today as A∞-bialgebras) was initiated by this author in a talk at Jim Stasheff’s 1996 schriftfest entitled “In Search of Higher Homotopy Hopf Algebras.” The idea in that talk was to think of a DG bialgebra as some (unknown) higher homotopy structure with trivial higher order structure and apply a graded version of Gerstenhaber and Schack’s b...
متن کاملBialgebra deformations of certain universal enveloping algebras
Let A denote a bialgebra over a field k and let At = A[[t]] denote the ring of formal power series with coefficients in A. Assume that A is a free algebra over k with a basis of primitives. We give a simple construction which makes At a bialgebra deformation of A. Usually At is neither commutative nor cocommutative. This construction yields deformations of bialgebras associated with families of...
متن کاملA simple construction of bialgebra deformations∗
Let A denote a bialgebra over a field k and let At = A[[t]] denote the ring of formal power series with coefficients in A. Assume that A is also isomorphic to a free, associative algebra over k. We give a simple construction which makes At a bialgebra deformation of A. In typical applications, At is neither commutative nor cocommutative. This construction yields bialgebra deformations associate...
متن کاملJ un 2 00 3 The CROCs , non - commutative deformations , and ( co ) associative bialgebras
We compactify the spaces K(m,n) introduced by Maxim Kontsevich. The initial idea was to construct an L∞ algebra governing the deformations of a (co)associative bialgebra. However, this compactification leads not to a resolution of the PROP of (co)associative bialgebras, but to a new algebraic structure we call here a CROC. It turns out that these constructions are related to the non-commutative...
