New explicit examples of Mannheim pair in 𝕃3
Abstract
In this paper, we construct explicit examples of Mannheim pairs, in the classical sense, in Minkowski 3-space 𝕃3, one for each of the five types of such pairs. In our main examples the Mannheim curve is neither a helix nor a slant helix. For each example we give the complete Frenet apparatus of both curves of the pair and their Cartesian coordinates in terms of elementary functions. The construction writes the tangent indicatrix in angular coordinates and uses a suitable auxiliary angle function, which reduces all the relevant integrals to elementary form; it is carried out both starting from the Mannheim curve and starting from its partner. In these coordinates, we also characterize the helices and the slant helices with timelike axis. We also prove, for the five types, that a Mannheim curve is a slant helix if and only if its partner is a helix, and we give an explicit example of such a pair.
