论文摘要
我们将为光滑函数$ y的Hessian决定因素提供一个简洁的公式：\ Mathbb r^n \supseteqΩ\ to \ mathbb r $，以便其图包含在二次hypersurface中。证明将大量使用矩阵代数。
We will give a concise formula for the Hessian determinant of a smooth function $y:\mathbb R^n\supseteqΩ\to\mathbb R$ such that its graph is contained in a quadratic hypersurface. The proof will make heavy use of matrix algebra.
