                "Elusive Effects of Gravitational Chern-Simons Terms"


                címmel tartandó szemináriumára.


Kivonat:

Gravitational Chern-Simons (gCS) Lagrangian terms appear in low-energy
effective actions coming from superstring theories and are used as
phenomenological extensions of general theory of relativity. Although 
they
have topological origin, gCS terms contribute to the equations of 
motion
with generalized Cotton tensor. However, it will be shown that this 
tensor
identically vanishes for "simple" metrics, thus leaving non-trivial
effects to the "complicated" cases. Furthermore, presence of gCS
Lagrangian terms makes contribution to the black hole entropy and, 
similar
to the equations of motion, these corrections are visible only with 
highly
"asymmetrical" black holes.
