Hi! Does somebody of you have Kapusta's book "finite temperature field theory" and Ashok Das book (same title)?

I'm quite sure there is a typo in one of them - compare the formulas for the fourier transformed thermal propagator:

Kapusta (3.22) and Ashok (1.30)

All the letters are the same but there is a missing minus-sign in front of the omega in Ashok's formula. Does somebody know where it comes from or which formula is the correct one?

Best regards
