Fermion on Curved Spaces, Symmetries, and Quantum Anomalies
Mihai Visinescu
We review the geodesic motion of pseudo-classical spinning particles in curved spaces. Investigating the generalized Killing equations for spinning spaces, we express the constants…
Nonholonomic Ricci Flows and Running Cosmological Constant: 3D Taub-NUT Metrics
Sergiu I. Vacaru, Mihai Visinescu
The common assertion that the Ricci flows of Einstein spaces with cosmological constant can be modelled by certain classes of nonholonomic frame, metric and linear connection defor…
Nonholonomic Ricci Flows and Running Cosmological Constant: I. 4D Taub-NUT Metrics
Sergiu I. Vacaru, Mihai Visinescu
In this work we construct and analyze exact solutions describing Ricci flows and nonholonomic deformations of four dimensional (4D) Taub-NUT spacetimes. It is outlined a new geomet…
Superalgebras of Dirac operators on manifolds with special Killing-Yano tensors
Ion I. Cotăescu, Mihai Visinescu
We present the properties of new Dirac-type operators generated by real or complex-valued special Killing-Yano tensors that are covariantly constant and represent roots of the metr…
