[institut] seminar grupe za cestice i gravitaciju

[Branislav Cvetkovic]

Postovane kolege,

u petak 15.11. u 11 h  na Institutu za fiziku, u sali 360,  Salvatore 
Capozziello (Universita di Napoli "Federico II") ce odrzati seminar
pod naslovom  "Cosmographic reconstruction to discriminate between 
modified
gravity and dark energy". Apstrakt vam prosledjujem u nastavku.

                                                   Pozdrav Branislav 
Cvetkovic

ABSTRACT: Cosmography is a model independent approach, useful to
discriminate among concurring cosmological scenarios. After reviewing
the main features and shortcomings of LCDM model, we propose a
cosmographic approach, based on some polynomial series like Pade',
Chebyschev, etc. to investigate  dark energy and modified gravity. The
main result is that series convergence seems a powerful tool to extend
the matching with the Hubble flow up to high redshift and then improve
the role of observers in Cosmology.
