Deformation of string topology into homotopy skein modules
Uwe Kaiser
Relations between the string topology of Chas and Sullivan and the homotopy skein modules of Hoste and Przytycki are studied. This provides new insight into the structure of homoto…
Strongly meager sets of size continuum
Tomek Bartoszynski, Saharon Shelah
We construct several models where there are no strongly meager sets of size continuum. In particular, there are no such sets in the Laver's model.
Hechler's theorem for the meager ideal
Tomek Bartoszynski, Masaru Kada
We prove the following theorem: For a partially ordered set Q such that every countable subset has a strict upper bound, there is a forcing notion satisfying ccc such that, in the…
Measuring the condensate fraction of rapidly rotating trapped boson systems: off-diagonal order from the density
Jairo Sinova, C. B. Hanna, A. H. MacDonald
We demonstrate a direct connection between the density profile of a system of ultra-cold trapped bosonic particles in the rapid-rotation limit and its condensate fraction. This con…
Hereditary topological diagonalizations and the Menger-Hurewicz Conjectures
Tomek Bartoszynski, Boaz Tsaban
We consider the question, which of the major classes defined by topological diagonalizations of open or Borel covers is hereditary. Many of the classes in the open case are not her…
Discovery of a Possible Anomalous X-ray Pulsar in the Small Magellanic Cloud
R. C. Lamb, D. W. Fox, D. J. Macomb +1
We report the serendipitous detection of a previously unreported pulsar from the direction of the Small Magellanic Cloud using data from the CHANDRA X-Ray Observatory. Because of t…
