Abstract
We prove a priori interior C2 estimate for σ_2 = f in R3, which generalizes Warren-Yuan's result.

Theorem 1
Let $u$ be a smooth solution to (eq:sigma2) on $B_{10}\subset\mathbb{R}^{3}$ with $\Delta u>0$. Then we have where $C$ depends only on $\|f\|_{C^{2}}$, $\|\frac{1}{f}\|_{L^{\infty}}$ and $||u||_{C^{1}}$.
