Cordas cósmicas e gravitação planar de ordem superior
(2008-02-29) [Tese de doutorado]
The possibility of generalizing gravity in 2+1 dimensions to include higher-derivative terms, thereby allowing for a dynamical theory, opens up a variety of new interesting questions. This is in great contrast with pure ...
Pure spinor superstring partition function
(2008-12-12) [Tese de doutorado]
In this thesis, we have calculated the partition function of pure spinors. The computation is performed by using two different methods, namely ghosts-for-ghosts (up to the twelth mass-level) and fixed point (up to the fifth ...
