Abstract:An extension of integral domains $${Rsubseteq S}$$ is said to have the “finite length of intermediate chains of domains” property (for short FICP) if each chain of intermediate rings between R and S is finite. The main purpose of this paper is to characterize when $${Rsubseteq S}$$ has FICP in case R * (the integral closure of R in S) is a finite dimensional semilocal domain. This generalizes a theorem due to Gilmer, in which S is the quotient field of R. Examples illustrating the sharpness and the limits of our results are settled.
Keywords:Ring extension  Intermediate chains of domains  Normal pair  Valuation domain
