[hep-th] seminari

[Branislav Cvetkovic]

Postovane kolege,


U okviru bilateralnog projekta "Gravitacija u kvantnom 
prostor-vremenu", prof. dr Fedele Lizzi (Università di Napoli Federico 
II) ce boraviti u Beogradu u periodu od 13. do 20. novembra i odrzati 
sledece seminare:

1. Petak, 14. novembar 2014, Institut za fiziku, 11 casova sala 300 
(ukoliko zbog izvodjenja gradjevinskih radova sala 300 bude nedostupna, 
seminar ce se odrzati u sali 10)

Spectral Geometry

I will introduce the view of geometry based on the algebraic approach. 
The formalism is built in such a way that it can be generalized to the 
case in which the algebra, implicitly defining the space,  is 
noncommutative, hence a ``noncommutative geometry''.
I will then discuss the natural action for these spaces, the spectral 
action, and some of its properties with respect to renormalization.


2. Sreda, 19. novembar 2014, Fizicki fakultet, 11 casova amfiteatar 661

Noncommutative Geometry and the standard model

I will introduce the approach to the standard model based on 
noncommutative geometry as pionereed by Chamseddine and Connes. I will 
(re)-introduce the spectral action, and its predictive power. I will 
then discuss the issues relating the gauge symmetries of the standard 
model and almost commutative geometries.


                                                                         
                       Pozdrav Branislav
