Hi, I'm doing the master in science and one of things that I have to study is the Gödel metric. His paper have a high level for me and I'm seeking theses and dissertations about the Gödel universe. At moment I got three theses about the subject in english and portuguese-BR and one dissertation in portuguese-BR. There are only a few theses about Gödel metric in portuguese and I can't find many theses in english because I don't know how to seek beyond the google. I would appreciate if somebody show me how to get some theses in english or spanish. I would appreciate too if somebody give me some text about the subject.
