The geodesic motion of pseudo-classical spinning particles in Euclidean Taub-NUT space is analysed. The constants of motion are expressed in terms of Killing-Yano tensors. Some previous results fromâ€¦ (More)

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 geometric techniques ofâ€¦ (More)

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 deformations resultingâ€¦ (More)

Fermions in D = 4 self-dual Euclidean Taub-NUT space are investigated. Dirac-type operators involving Killing-Yano tensors of the Taub-NUT geometry are explicitly given showing that they anticommuteâ€¦ (More)

We investigate quantum anomalies for generalized Euclidean TaubNUT metrics which admit hidden symmetries analogous to the RungeLenz vector of the Kepler-type problem. We review results which showâ€¦ (More)

A necessary condition that a StÃ¤ckel-Killing tensor of valence 2 be the contracted product of a Killing-Yano tensors of valence 2 with itself is re-derived for a Riemannian manifold. This conditionâ€¦ (More)

A novel automatic QRS detection algorithm that is based on a wavelet pre-filter and an adaptive threshold technique is presented. The algorithm utilizes a bi-orthogonal wavelet filter to de-noise theâ€¦ (More)

The algebra of conserved observables of the SO(4, 1) gauge-invariant theory of the Dirac fermions in the external field of the KaluzaKlein monopole is investigated. It is shown that the Diracâ€¦ (More)

We compute the axial anomaly for the Taub-NUT metric on R. We show that the axial anomaly for the generalized Taub-NUT metrics introduced by Iwai and Katayama is finite, although the Dirac operatorâ€¦ (More)

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 of motion in termsâ€¦ (More)
