Invariants of topological spaces of dimension three play a major role in many areas, in particular . . . Introduction by the Organisers The workshop Invariants of topological spaces of dimension three, organised by Max Muster (München) and Bill E. Xample (New York) was well attended with over 30 participants with broad geographic representation from all continents. This workshop was a nice blen...

Many models of supersymmetry breaking involve particles with weak scale mass and Planck mass suppressed couplings. Coherent production of such particles in the early universe destroys the successful predictions of nucleosynthesis. We show that this problem may be solved by a brief period of weak scale inflation. Furthermore the inflaton potential for such an inflation naturally arises from the ...

We consider coherent and mixed reliability systems composed of elements with independent and identically distributed lifetimes. We present upper bounds on variances of system lifetimes, expressed in terms of variances of single components. We also discuss attainability conditions and some special cases and examples.

It is shown that the even and odd coherent light and other nonclassical states of light like superposition of coherent states with different phases may replace the squeezed light in interferometric gravitational wave detector to increase its sensitivity.

Development of a Coherent THz Magneto-Spectroscopy System

A non group theoretic proof of completeness of arbitrary coherent states D(α) | f > Abstract A new proof for the completeness of the coherent states D(α) | f > for the Heisenberg Weyl group and the groups SU (2) and SU (1, 1) is presented. Generalizations of these results and their consequences are disussed.
