متن کاملGeoff Goehle Tuesday May 26 , 2009
We present a number of findings concerning groupoid dynamical systems and groupoid crossed products. The primary result is an identification of the spectrum of the groupoid crossed product when the groupoid has continuously varying abelian stabilizers and a well behaved orbit space. In this case, the spectrum of the crossed product is homeomorphic, via an induction map, to a quotient of the spe...

One of the main points of the paper is the importance of addressing conflicts of interest in a way that will not reduce the information flow to financial markets. While a number of remedies are already in place, putting the bubble and fraud into a somewhat broader perspective, in order to avoid further remedies that might do more harm than good, could be worthwhile. Although one would not want ...
متن کاملParker weights revisited.
The short-scan case in fan-beam computed tomography requires the introduction of a weighting function to handle redundant data. Parker introduced such a weighting function for a scan over pi plus the opening angle of the fan. In this article we derive a general class of weighting functions for arbitrary scan angles between pi plus fan angle and 2pi (over-scan). These weighting functions lead to...
