In this presentation, I will address contrasting views on contradicting issues regarding multilingualism at Sveriges (3–5 år) egna uppfattningar om språk.

The Sundman stability is investigated. The Sundman stability of the motion of the Moon in the general three-body problem of the Sun-Earth-Moon is established. cal dynamics, chaos, instabilities. the three-body problem are relevant to the helium atom and water. molecule [2]. The three-body problem admits many ‘regular’ solutions such as. the collinear and equilateral periodic solutions of Euler and La-. grange as well as the more recently discovered ﬁgure-8 solution.

Moreover, Waldvogel ( 1980 ) considered the variational equations of the three-body problem with triple collisions and obtained solutions given in terms of hypergeometric functions, which are valid in the vicinity of the collision. solution to the three-body problem, of a type which mathematicians such as Poincaré had believed impossible to achieve. Although lauded at the time, the result dimmed from view as the twentieth century progressed and its significance was often overlooked.

A new coordinate form for the Sundman surfaces is obtained. Singular points of the surfaces are determined and constructed. The three-body problem in celestial mechanics consists in determining the positions and trajec- tories of distinct bodies in past and future times.

A new method for studying the Hill-type stability in the general three-body problem using Sundman’s inequality is presented. Sundman’s surfaces in 3D space are constructed, which are counterparts of Hill’s surfaces. The conditional and unconditional Sundman stability criteria are established and used for determining the stability regions.
