Braided Lie algebras and bicovariant differential calculi over coquasitriangular Hopf algebras

X. Gomez, S. Majid

We show that if $g_{Γ}$ is the quantum tangent space (or quantum Lie algebra in the sense of Woronowicz) of a bicovariant first order differential calculus over a coquasitriangular H…

Noncommutative cohomology and electromagnetism on $C_{q} [S L_{2}]$ at roots of unity

X. Gomez, S. Majid

We compute the noncommutative de Rham cohomology for the finite-dimensional q-deformed coordinate ring $C_{q} [S L_{2}]$ at odd roots of unity and with its standard 4-dimensional differe…
