A spectrophotometric catalogue of HII galaxies
Cristina C. Popescu, Ulrich Hopp
We present a spectrophotometric catalogue of 90 emission-line galaxies (ELGs) discovered during an objective - prism survey that aimed to search for dwarf galaxies within the voids…
Ternary configuration in the framework of inverse mean-field method
V. G. Kartavenko, A. Sandulescu, W. Greiner
A static scission configuration in cold ternary fission has been considered in the framework of mean field approach. The inverse scattering method is applied to solve single-partic…
Disks with Jet, ADAF, or EDAF for Sgr A*
A. C. Donea, Heino Falcke, P. L. Biermann
We investigate various models of accretion disks for Sgr A*, one of the most puzzling sources in the Galaxy. The generic image we have taken into account consists of a black hole,…
Topological Entropy for the Canonical Endomorphism of Cuntz-Krieger Algebras
Florin P. Boca, Paul Goldstein
It is shown that Voiculescu's toplogical entropy for the canonical endomorphism of a simple Cuntz-Krieger algebra O_A equals the logarithm of the spectral radius of A.
Classical limit of Lie groupoid C^*-algebras
Birant Ramazan
Let G be a Lie groupoid and L his Lie algebroid. We give a definition of the classical limit of a C^*-bundle and we use the tangent groupoid associated to G to show that the Poisso…
