A homology plane of general type can have at most a cyclic quotient singularity
R. V. Gurjar, M. Koras, M. Miyanishi +1
We show that a homology plane of general type has at worst a single cyclic quotient singular point. An example of such a surface with a singular point does exist. We also show that…
Affine threefolds admitting -actions
R. V. Gurjar, M. Koras, M. Miyanishi +1
Affine varieties of dimension greater than two can be explored their structures with the help of fibrations by the affine line or plane and quotient morphisms by -act…
Beating the spin-down limit on gravitational wave emission from the Crab pulsar
The LIGO Scientific Collaboration, B. Abbott, R. Abbott +440
We present direct upper limits on gravitational wave emission from the Crab pulsar using data from the first nine months of the fifth science run of the Laser Interferometer Gravit…
-fibrations on affine threefolds
R. V. Gurjar, M. Koras, K. Masuda +2
The affine line minus one point is the underlying space of the algebraic torus of dimension one. However the fibration of an affine algebraic threefold by the affine line minus one…
Searches for gravitational waves from known pulsars with S5 LIGO data
The LIGO Scientific Collaboration, The Virgo Collaboration, B. P. Abbott +678
We present a search for gravitational waves from 116 known millisecond and young pulsars using data from the fifth science run of the LIGO detectors. For this search ephemerides ov…
Search for gravitational-wave bursts associated with gamma-ray bursts using data from LIGO Science Run 5 and Virgo Science Run 1
LIGO Scientific Collaboration, Virgo Collaboration, B. P. Abbott +665
We present the results of a search for gravitational-wave bursts associated with 137 gamma-ray bursts (GRBs) that were detected by satellite-based gamma-ray experiments during the…
