报告摘要:I will discuss the interior C2 estimate for σ2 equation in dimension 3. In my paper (arXiv:1711.00948), I proved a doubling lemma which is key to study the interior C2 estimate for σ2 equations. Recently, Shanker and Yuan use this doubling lemma to prove the interior C2 estimate in dimension 4.
