T. Inagaki et al., EXACT SOLUTION OF THE EQUATION FOR SPINOR 2-POINT FUNCTIONS IN THE EINSTEIN UNIVERSE, Progress of theoretical physics, 96(4), 1996, pp. 847-852
The two-point function for spinor fields is investigated in the Einste
in universe (R circle times S-N-1). An equation for the massive spinor
two-point function is solved in an exact manner and an explicit expre
ssion is given for the two-point function. It is shown that the simple
r expression emerges for the massless case.
