نویسندگان

چکیده

In the second part of his prize-winning essay 1729, Bouguer (1698–1758) considers a light ray in spherically symmetric medium and introduces invariant named after him. He deduces an expression refraction integral, leading to table which is computed for particular atmospheric model. then studies influence ray’s curvature on horizon dip predicts hillingar effect. As complement, we recall that Bradley formula can be derived from This helps understand strong convexity horizontal versus refractivity.

La Résolvante de Lagrange et ses Applications

In this paper, the changes of representations of a group are used in order to describe its action as algebraic Galois group of an univariate polynomial on the roots of factors of any Lagrange resolvent. By this way, the Galois group of resolvent factors are pre-determinated. In follows, different applications are exposed; in particular, some classical results of algebraic Galois theory.
