摘要

We study propagation of singularities for the Hamilton-Jacobi equation where is a positive definite quadratic form. Each viscosity solution is semiconcave, and it is known that its singularities move along generalized characteristics. We give a new proof of the recent result by Cannarsa et al. (Discrete Contin Dyn Syst 35:4225-4239, 2015), namely that the singularities propagate along generalized characteristics indefinitely forward in time.
