Research output: Other contributionResearch


We investigate the quantum twistor bundle constructed as a U(1)-quotient of the quantum instanton bundle of Bonechi, Ciccoli and Tarlini. It is an example of a locally trivial noncommutative bundle fulfilling conditions of the framework recently proposed by Brzezinski and Szymanski. In particular, we give a detailed description of the corresponding C∗-algebra of ‘continuous functions’ on its noncommutative total space. Furthermore, we analyse a different construction of a quantum instanton bundle due to Landi, Pagani and Reina, find a basis of its polynomial algebra and discover an intriguing and unexpected feature of its enveloping C∗-algebra.
