Özet

A spectral representation for the Green's functions of the free fermionic Ramond-Neveu-Schwarz string is obtained. This representation is valid for any initial and final string configurations and it manifests an exponential growth of spectral densities intrinsic in nonlocalizable theories. The causal and singular properties of the propagators are considered.
