In this paper, we investigate the spectra of invertible weighted composition
operators with automorphism symbols, on Hardy space H2(BN) and
weighted Bergman spaces Aα2(BN), where BN is the
unit ball of the N-dimensional complex space. By taking N=1,
BN=D the unit disc, we also complete the discussion about
the spectrum of a weighted composition operator when it is invertible on
H2(D) or Aα2(D).Comment: 23 Page
