A Note on Dirac Operators on the Quantum Punctured Disk

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We study quantum analogs of the Dirac type operator −2z∂/∂z on the punctured disk, subject to the Atiyah-Patodi-Singer boundary conditions. We construct a parametrix of the quantum operator and show that it is bounded outside of the zero mode.

Yang-Mills field from fuzzy sphere quantum Kaluza-Klein model

open access: yesJournal of High Energy Physics
Using the framework of quantum Riemannian geometry, we show that gravity on the product of spacetime and a fuzzy sphere is equivalent under minimal assumptions to gravity on spacetime, an su 2-valued Yang-Mills field A μi and a real-symmetric-matrix ...
