报告摘要:
The classical definitions of envelopes are vague for singular plane curves. In order to define envelopes for singular curves, we introduce a one-parameter family of Legendre curves in the unit tangent bundle. Then we give a definition of envelope for one-parameter families of Legendre curves. In this talk, I will discuss properties and give examples of envelopes.
