We calculate explicitly an adelic quotient group for an excellent Noetherian normal integral two-dimensional separated scheme. An application to an irreducible normal projective algebraic surface over a field is given.Recently there were also found the interesting connections and interactions with many questions between the higher adeles theory and the Langlands program, see [16].As an application, we deduce from our calculations of adelic quotient group (2) the corresponding quotient group when X is a projective irreducible normal surface over a field k , and C is the support of an ample divisor. As in the one-dimensional case, this quotient group will be a linearly compact k -vector space. We note that this quotient group when the surface X is smooth and the sheaf F = O X was calculated in [12, § 14].
