摘      要：Let O_L and O_K denote the rings of integers in the algebraic number fields L and K, respectively, where K is a subfield of L. If O_L is a free O_K-module, then L/K is said to have a relative integral basis. Artin and Frhlich raised and studied the problem of existence of a relative integral basis for a number field L. The nroblem was treated
