Examples of quantum braided groups

Hlavatý, Ladislav (1994)

Proceedings of the Winter School "Geometry and Physics"

Summary: The author gives the defining relations of a new type of bialgebras that generalize both the quantum groups and braided groups as well as the quantum supergroups. The relations of the algebras are determined by a pair of matrices ( R , Z ) that solve a system of Yang-Baxter-type equations. The matrix coproduct and counit are of standard matrix form, however, the multiplication in the tensor product of the algebra is defined by virtue of the braiding map given by the matrix Z . Besides simple solutions...

Exemples de feuilletages de Lie

Hamidou Dathe, Jean-François Quint (2006)

Annales de la faculté des sciences de Toulouse Mathématiques

Nous donnons des exemples de feuilletages de Lie sur une variété compacte qui ne se déforment pas en des feuilletages de Lie à holonomie discrète.

Exotic characteristic classes and subfoliations

Luis A. Cordero, P. M. Gadea (1976)

Annales de l'institut Fourier

A topological obstruction for a foliation F 1 be a sub-foliation of another F 2 is given by comparing the images of the associated characteristic homomorphisms (in the sense of Lehmann).
