Zdravo svima,

evo najave seminara, koji ce u petak 25. marta 2022. odrzati Branislav 
Cvetkovic (Institut za fiziku)

Naslov: Entropy in Poincaré gauge theory: Hamiltonian approach

Asptrakt: Canonical generator G of local symmetries in Poincaré gauge 
theory is constructed as an integral over a spatial section Σ of 
spacetime. Its regularity (differentiability) on the phase space is 
ensured by adding a suitable surface term, an integral over the boundary 
of Σ at infinity, which represents the asymptotic canonical charge. For 
black hole solutions, Σ has two boundaries, one at infinity and the 
other at horizon. It is shown that the canonical charge at horizon 
defines entropy, whereas the regularity of G implies the first law of 
black hole thermodynamics.
