约束流形上的Hessian算子

Hessian Operators on Constraint Manifolds

Petre Birtea, Dan Comănescu

摘要:

在约束流形上,我们给出了费用函数的Hessian矩阵的一个显式公式,它涉及到延拓函数的Hessian矩阵和约束函数的黑塞矩阵.对于正交群${\bf O}(n)$,我们只使用$\mathbb{R}^{n^2}$上的欧几里德坐标,给出了一个显式公式.对${\bf SO}(3)$进行了最优化问题。分析了它在非线性稳定性问题中的应用。

英文摘要:

On a constraint manifold we give an explicit formula for the Hessian matrix of a cost function that involves the Hessian matrix of a prolonged function and the Hessian matrices of the constraint functions. We give an explicit formula for the case of the orthogonal group ${\bf O}(n)$ by using only Euclidean coordinates on $\mathbb{R}^{n^2}$. An optimization problem on ${\bf SO}(3)$ is completely carried out. Its applications to nonlinear stability problems are also analyzed.
