Using the simple path integral method we calculate the n-point functions of
field strength of Yang-Mills theories on arbitrary two-dimensional Riemann
surfaces. In U(1)
case we show that the correlators consist of two parts, a
free and an x-independent part. In the case of non-Abelian semisimple compact
gauge groups we find the nongauge-invariant correlators in Schwinger-Fock
gauge and show that it is also divided to a free and an almost x-independent
part. We also find the gauge-invariant Green
functions and show that they correspond to a free field theory.
