Magnetic Pseudodifferential Operators
Viorel Iftimie, Marius Mantoiu, Radu Purice
In previous papers, a generalization of the Weyl calculus was introduced in connection with the quantization of a particle moving in under the influence of a variable…
On the Intervals of a Third between Farey Fractions
Cristian Cobeli, Alexandru Zaharescu
The spacing distribution between Farey points has drawn attention in recent years. It was found that the gaps between consecutive elements of the Farey sequence produ…
Some Exact Sequences for Toeplitz Algebras of Spherical Isometries
Bebe Prunaru
A family of commuting Hilbert space operators is said to be a spherical isometry if in the weak operator topology. We show that every c…
Structure in the radio counterpart to the 2004 Dec 27 giant flare from SGR 1806-20
R. P. Fender, T. W. B. Muxlow, M. A. Garrett +7
On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this…
-index of the Dirac operator of generalized Euclidean Taub-NUT metrics
Sergiu Moroianu, Mihai Visinescu
We compute the axial anomaly for the Taub-NUT metric on . We show that the axial anomaly for the generalized Taub-NUT metrics introduced by Iwai and Katayama is finite, althou…
A quadratic rate of asymptotic regularity for CAT(0)-spaces
Laurentiu Leustean
In this paper we obtain a quadratic bound on the rate of asymptotic regularity for the Krasnoselski-Mann iterations of nonexpansive mappings in CAT(0)-spaces, whereas previous resu…
