Explicit Hopf-Galois description of -induced Frobenius homomorphisms
L. Dabrowski, P. M. Hajac, P. Siniscalco
The exact sequence of ``coordinate-ring'' Hopf algebras A(SL(2,C)) -> A(SL_q(2)) -> A(F) determined by the Frobenius map Fr, and the same way obtained exact sequence of (quantum) B…
A Finite Quantum Symmetry of M(3,C)
Ludwik Dabrowski, Fabrizio Nesti, Pasquale Siniscalco
The 27-dimensional Hopf algebra A(F), defined by the exact sequence of quantum groups A(SL(2,C))->A(SL_q(2))->A(F), q^3=1, is studied as a finite quantum group symmetry of the matr…
On the Drinfeld Twist for Quantum sl(2)
L. Dabrowski, F. Nesti, P. Siniscalco
An isomorphism, up to a twist, between the quasitriangular quantum enveloping algebra U_h(sl(2)) and the (classical) U(sl(2))[[h]]is discussed. The universal twisting element $\cal…
Metrics and Pairs of Left and Right Connections on Bimodules
L. Dcabrowski, P. M. Hajac, G. Landi +1
Properties of metrics and pairs consisting of left and right connections are studied on the bimodules of differential 1-forms. Those bimodules are obtained from the derivation base…
