A Weyl Calculus on Symplectic Phase Space
Maurice De Gosson
We study the twisted Weyl symbol of metaplectic operators; this requires the definition of an index for symplectic paths related to the Conley-Zehnder index. We thereafter define a…
On the Weyl Representation of Metaplectic Operators
Maurice De Gosson
We study the Weyl representation of metaplectic operators associated to a symplectic matrix having no non-trivial fixed point, and justify a formula suggested in earlier work of Me…
Graphs and colorings for answer set programming
Kathrin Konczak, Thomas Linke, Torsten Schaub
We investigate the usage of rule dependency graphs and their colorings for characterizing and computing answer sets of logic programs. This approach provides us with insights into…
Network Synchronization, Diffusion, and the Paradox of Heterogeneity
Adilson E. Motter, Changsong Zhou, Juergen Kurths
Many complex networks display strong heterogeneity in the degree (connectivity) distribution. Heterogeneity in the degree distribution often reduces the average distance between no…
A VLBI Study of the Gravitational Lens JVAS B0218+357
R. Mittal, R. Porcas, O. Wucknitz +1
We present the results of phase-referenced VLBA+Effelsberg observations at five frequencies of the gravitational lens B0218+357 to establish the precise registration of the A and B…
