Polypolar coordination and symmetries

 pdf (908K)  / List of references

The polypolar system of coordinates is formed by a family of a parametrized on a radius isofocal of kf-lemniscates. As well as the classical polar system of coordinates, it characterizes a point of a plane by a polypolar radius ρ and polypolar angle φ. For anyone connectedness a family isometric of curve ρ = const – lemniscates and family gradient of curves φ = const – are mutually orthogonal conjugate coordinate families. The singularities of polypolar coordination, its symmetry, and also curvilinear symmetries on multifocal lemniscates are considered.

Keywords: curves, focuses, multifocal lemniscates, Cassini ovals, polar system of coordinates, coordinate families, groups of symmetries, curvilinear symmetries
