Abstract
Two-point functions for scalar and spinor fields are investigated in Einstein universe (). Equations for massive scalar and spinor two-point functions are solved and the explicit expressions for the two-point functions are given. The simpler expressions for massless cases are obtained both for the scalar and spinor cases.
