In Euclidean field theory, they becomes respectively the Euclidean Green's functions $G_{\infty}$ and $G_{\2π}$, whose we give different suitable forms. In the case of the massive spin-$\frac{1}{2}$ field, we determine also the Euclidean spinor Green's function $S_{\infty}$ and $S_{\2π}$ in different suitable forms. In both cases for massless fields in four dimensions, we compute the vacuum expectation value of the energy-momentum tensor relative to the Rindler observer.18 pages, latex, no figuresGeneral Relativity and Quantum Cosmologytext
