报告摘要：Weyl's lemma states that every weak solution of Laplace's equation is also a smooth solution. We find that there is no Weyl's lemma for 2-Hessian equations. For any α small, we construct infinitely many C 1,α very weak solutions to the 2- Hessian equation with prescribed boundary value. This is joint work with Tongtong Li.
