Special isothermic surfaces (part II)
Sala B3-01

Susana Santos (CMAF/FCUL)

Abstract:

We will introduce the classical notion and an invariant formulation of isothermic surfaces. Under these two approaches, the Christoffel transforms and the Darboux transforms of an isothermic surface will be discussed. We will also present the 2-dimensional sphere congruences used throughout these seminars.
