A Note on Spectral Triples on the Quantum Disk
Slawomir Klimek, Matt McBride, John Wilson Peoples
By modifying the ideas from our previous paper [SIGMA 13 (2017), 075, 26 pages, arXiv:1705.04005], we construct spectral triples from implementations of covariant derivations on th…

Derivations and Reflection Positivity on the Quantum Cylinder
Slawomir Klimek, Matt McBride
We describe the general structure of unbounded derivations in the quantum cylinder. We prove a noncommutative analog of reflection positivity for Laplace-type operators in a noncom…
