On fundamental units of certain fields. (Russian) Zbl 0768.11050
The paper describes practical computational methods for finding the fundamental units in totally real fields of degree $$\leq 4$$. The fundamental units are (or can be directly obtained from) successive minima of some functions depending on the coefficients of the minimal polynomials of algebraic numbers.
