摘要

We start with a zero-dimensional frame L and an arbitrary integral domain A. We equip A with the discrete topology and consider the ring of A-valued continuous functions on L, which we denote by \(A_dL\) A d L . In this article, we classify both the classical ring of quotients and maximal ring of quotients of \(A_dL\) A d L , paying special attention to the case of \({\mathfrak Z}L\) Z L the integer-valued continuous functions on L.
