An interior second derivative bound for solutions of Hessian equations
In previous work we showed that weak solutions in W2,p(Ω) of the k-Hessian equation Fk[u] = g(cursive chi) have locally bounded second derivatives if g is positive and sufficiently smooth and p > kn/2. Here we improve this result to p > k(n - 1)/2, which
