Non-linear sigma-models in noncommutative geometry: fields with values in finite spaces
Ludwik Dabrowski, Thomas Krajewski, Giovanni Landi
We study sigma-models on noncommutative spaces, notably on noncommutative tori. We construct instanton solutions carrying a nontrivial topological charge q and satisfying a Belavin…

U_{q}(sl_{2}) at fourth root of unity
D. Kastler, T. Krajewski, P. Seibt +1
In this paper, we study finite dimensional quotients of the Hopf algebra U_{q}(sl_{2}) at fourth root of unity. We give explicitly all the corresponding automorphisms, real forms a…
