FOCAL SURFACES OF WAVE FRONTS IN THE EUCLIDEAN 3-SPACE
Published online by Cambridge University Press: 13 July 2018
Abstract
We characterise singularities of focal surfaces of wave fronts in terms of differential geometric properties of the initial wave fronts. Moreover, we study relationships between geometric properties of focal surfaces and geometric invariants of the initial wave fronts.
