The Biderivative and a ∞ -bialgebras
نویسنده
چکیده
An A∞-bialgebra is a DGM H equipped with structurally compatible operations { ω : H → H } such that ( H, ω ) is an A∞-algebra and ( H, ω ) is an A∞-coalgebra. Structural compatibility is controlled by the biderivative operator Bd, defined in terms of two kinds of cup products on certain cochain algebras of pemutahedra over the universal PROP U = End (TH). To Jim Stasheff on the occasion of his 68th birthday.

متن کاملDouble Bicrossproduct Lie Bialgebras
We construct double biproduct, bicrossproduct, double crossproduct, double bicrossproduct Lie bialgebras from braided Lie bialgebras. The relations between them are found. The main result generalizes Majid’s matched pair of Lie algebras, Drinfeld’s quantum double of Lie bialgebras, and Masuoka’s cross product Lie bialgebras. Some properties of double biproduct Lie bialgebras are given. In the a...
متن کاملBraided Lie Bialgebras
We introduce braided Lie bialgebras as the infinitesimal version of braided groups. They are Lie algebras and Lie coalgebras with the coboundary of the Lie cobracket an infinitesimal braiding. We provide theorems of transmutation, Lie biproduct, bosonisation and double-bosonisation relating braided Lie bialgebras to usual Lie bialgebras. Among the results, the kernel of any split projection of ...
متن کاملDouble Cross Biproduct and Bicycle Bicrossproduct Lie Bialgebras
We construct double cross biproduct and bicycle bicrossproduct Lie bialgebras from braided Lie bialgebras. The main result generalizes Majid’s matched pair of Lie algebras, Drinfeld’s quantum double, and Masuoka’s cross product Lie bialgebras. 2000 Mathematics Subject Classification: 17B62, 18D35
متن کاملCoquasitriangular Hopf Algebras in Braided Categories
We study (Hopf) bialgebras in a braided category, which are equipped with an inner twist. By means of the inner twist we define the second mutiplication on the (Hopf) bialgebra, which plays the role of the opposite multiplication. Hence one can define the coquasitriangular structure on these bialgebras. Examples of these bialgebras are reconstructed bialgebras.
