Polypolar coordination and symmetries

Abstract: Полиполярная система координат формируется семейством параметризованных по радиусу изофокусных kf-лемнискат. Как и классическая полярная система координат, она характеризует точку плоскости полиполярным радиусом ρ и полиполярным углом ϕ. Для любой связности семейство изометрических кривых ρ = const -лемнискат и семейство градиентных кривых ϕ = const являются взаимно ортогональными сопряженными координатными семействами. Рассмотрены особенности полиполярной координации, ее симметрии, а также криволинейные симме… Show more

“…The building of symmetric closed curves with two or more foci, i.e., figures like ellipses, Perseus curves, Cayley ovals, and lemniscates, is of particular practical interest [14][15][16][17][18]. Some of these curves are well studied, such as special cases of Perseus curves, Cassini ovals, Bernoulli lemniscate, and Booth lemniscate, and are applied to radiolocation, group theory, cluster analysis, engineering and construction design, and quantum physics [19][20][21][22][23][24][25].…”
