Focal surfaces of wave fronts in the Euclidean 3-space

Published 17 Apr 2018 in math.DG | (1804.06123v1)

Abstract: We characterize 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.
