Seifert fiber space is a PFB. The theorem states that every principal fiber bundle (PFB) admits a connection form, so how can we define the connection 1-form on it? Or how can I find a book or article about the subject?

Try Kobayashi and Nozumi's Differential Geometry, or Morita's "Geometry of Differential Forms; look up "Ehresmann Connection" in the index. –  user99680 Dec 29 '13 at 0:06
