The Isospectral Dirac Operator on the 4-dimensional Orthogonal Quantum Sphere
Francesco D'Andrea, Ludwik Dabrowski, Giovanni Landi
Equivariance under the action of Uq(so(5)) is used to compute the left regular and (chiral) spinorial representations of the algebra of the orthogonal quantum 4-sphere S^4_q. These…
Examples of noncommutative instantons
Giovanni Landi
These notes aim at a pedagogical introduction to recent work on deformation of spaces and deformation of vector bundles over them, which are relevant both in mathematics and in phy…
Noncommutative Bundles and Instantons in Tehran
Giovanni Landi, Walter van Suijlekom
We present an introduction to the use of noncommutative geometry for gauge theories with emphasis on a construction of instantons for a class of four dimensional toric noncommutati…
Noncommutative instantons from twisted conformal symmetries
Giovanni Landi, Walter D. van Suijlekom
We construct a five-parameter family of gauge-nonequivalent SU(2) instantons on a noncommutative four sphere and of topological charge equal to -1. These instantons are cri…
