21st Century COE Program : Mathematics of Nonlinear Structure via Singularity

Kentaro Saji : The 13th COE Lecture Series

Fronts and its singularities

Fronts in 3-dimensional space are surfaces with singularities in it, whose unit normal vectors are well-defined. Since they have the unit normal vector, they have good affinity to classical geometry. In this COE Lecture series, we introduce useful criteria for some singularities of fronts and present some applications.
