Hopf algebroids and twists for quantum projective spaces

Ludwik Dabrowski, Giovanni Landi, Jacopo Zanchettin

We study the relationship between antipodes on a Hopf algebroid $H$ in the sense of Böhm-Szlachanyi and the group of twists that lies inside the associated convolution al…

Levi-Civita connections on quantum spheres

Joakim Arnlind, Kwalombota Ilwale, Giovanni Landi

We introduce $q$ -deformed connections on the quantum 2-sphere and 3-sphere, satisfying a twisted Leibniz rule in analogy with $q$ -deformed derivations. We show that such connection…

Gauge groups and bialgebroids

Xiao Han, Giovanni Landi

We study the Ehresmann--Schauenburg bialgebroid of a noncommutative principal bundle as a quantization of the gauge groupoid of a classical principal bundle. We show that the gauge…

Levi-Civita connections and vector fields for noncommutative differential calculi

Jyotishman Bhowmick, Debashish Goswami, Giovanni Landi

We study covariant derivatives on a class of centered bimodules $E$ over an algebra A. We begin by identifying a $Z (A)$ -submodule $X (A)$ which…

On the Koszul formula in noncommutative geometry

Jyotishman Bhowmick, Debashish Goswami, Giovanni Landi

We prove a Koszul formula for the Levi-Civita connection for any pseudo-Riemannian bilinear metric on a class of centered bimodule of noncommutative one-forms. As an application to…
