N2 - We consider the correlation functions in a gas of electrons moving within a thin layer on the surface of nanosize sphere. A closed form of expressions for the Ruderman-Kittel-Kasuya-Yosida (RKKY) indirect exchange, superconducting Cooper loop and “density-density” correlation function is obtained. The systematic comparison with planar results is made, the effects of spherical geometry are outlined. The quantum coherence of electrons leads to the enhancement of all correlations for the points-antipodes on the sphere. This effect is lost when the radius of the sphere exceeds the temperature coherence length.
