The spiral minimal surfaces and their Legendre and Weierstrass representations

Publikováno v: Differential Geometry and its Applications, 26(1), 23-41

A class of spiral minimal surfaces in E3 is constructed using a symmetry reduction. The reduction leads to a cubic-nonlinear ODE whose phase portrait is described using an auxiliary Riccati's equation and the Warzewski topological principle for its s
