摘要
本文得到Lie群上某些乘积结构下投影的导数,推广了Bhatia和Mukherjea的关于非奇异矩阵的QR与极分解下投影导数的结果.
We obtain the derivatives of projections under certain group product structures on Lie groups, extending some matrix results of Bhatia and Mukherjea on the derivatives of projections with respect to the QR and polar decompositions of a nonsingular matrix.
