Hopf–Rinow theorem is a set of statements about the geodesic completeness of Riemannian manifolds. It is named after Heinz Hopf and his student Willi Rinow, who published it in 1931. Stefan Cohn-Vossen extended part of the Hopf–Rinow theorem to the context of certain types of metric spaces.

Recall that if Φ is a matrix function in L∞ (Mn,n ) such that the Toeplitz operator TΦ is Fredholm, then by Simonenko’s theorem [S], Φ admits the factorization (1.2) Φ = Ψ∗2 …
WebFollowing this idea, we reach the following Hopf-Lax formula: u(t,x)= z(t)= inf y∈ Rn n tL x − y t + g(y) o. (30) Remark 2. It can be shown that L grows superlinearly at infinity. As a consequence, if we assume g to be Lipschitz continuous, then the infimum is actually a minimum. 2 Math 527 Lecture 6: Hamilton-Jacobi Equation: Explicit ...
