7 N ov 2 00 8 Higher order invariants , cohomology , and automorphic forms

A general structure theorem on higher order invariants is proven. For an arithmetic group, the structure of the corresponding Hecke module is determined. It is shown that the module does not contain any irreducible submodule. This explains the fact that L-functions of higher order forms have no Euler-product. Higher order cohomology is introduced, classical results of Borel are generalized and ...

In this preliminary study we investigate the effects of using different equations of state (CEFF and OPAL) in the calibration of the binary system α Centauri. Constraints coming from the detection of acoustic oscillations in α Centauri A and B are included in the modelling.

The occurence of “exotic” shapes in light N=Z α-like nuclei is investigated for 24Mg+12C and 32S+24Mg. Various approaches of superdeformed and hyperdeformed bands associated with quasimolecular resonant structures with low spin are presented. For both reactions, exclusive data were collected with the Binary Reaction Spectrometer in coincidence with EUROBALL IV installed at the VIVITRON Tandem f...
