Chandra HRC Localization of the Low Mass X-ray Binaries X1624-490 and X1702-429: The Infrared Counterparts
S. Wachter, J. W. Wellhouse, S. K. Patel +3
We report on the precise localization of the low mass X-ray binaries X1624-490 and X1702-429 with the Chandra HRC-I. We determine the best positions to be 16:28:02.825 -49:11:54.61…
The LSB theorem implies the KKM lemma
Gwen Spencer, Francis Edward Su
We prove the lemma of Knaster-Kuratowski-Mazurkiewicz as a consequence of the Lusternik-Schnirelman-Borsuk theorem.
Are classically singular spacetimes quantum mechanically singular as well?
D. A. Konkowski, T. M. Helliwell, V. Arndt
Are the classical singularities of general relativistic spacetimes, normally defined by the incompleteness of classical particle paths, still singular if quantum mechanical particl…
Definition and classification of singularities in GR: classical and quantum
D. A. Konkowski, T. M. Helliwell
We will briefly review the definition and classification of classical and quantum singularities in general relativity. Examples of classically singular spacetimes that do not have…
Quantum singularity of Levi-Civita spacetimes
D. A. Konkowski, T. M. Helliwell, C. Wieland
Quantum singularities in general relativistic spacetimes are determined by the behavior of quantum test particles. A static spacetime is quantum mechanically singular if the spatia…
