U utorak 7. siječnja s početkom u 14:15h (u prostoriji F-201 na FO) prof. Rodrigo Olea (UNAB, Čile) održat će predavanje pod naslovom "Kounterterms in anti-de Sitter gravity".
As an alternative to the holographic renormalization procedure in the context
of AdS/CFT correspondence, we introduce a regularization scheme for AdS gravity
based on the addition boundary terms which are a given polynomial of the
extrinsic and intrinsic curvatures (kounterterms). Since these terms are closely
related to either topological invariants or Chern-Simons densities in the corresponding
dimension, they can be easily generalized to other gravity theories
(Einstein–Gauss–Bonnet, Lovelock, etc.). Finally, a general prescription on how
to obtain the standard counterterm series in AdS gravity is given.
