Now, since

v λ satisfies in the viscosity sense

which implies, together with the coercivity of H, the equi-Lipschitz continuity of . Thus the collections and of functions on are relatively compact in . We may select a sequence such that

for some functions as j → ∞, where the convergences to v and w are uniform on . Observe that for all ,

which shows that w is constant on . If we write this constant as a, then we see by Proposition 1.9 that v is a viscosity solution of (EVP). This completes the proof of (i). □
