Alberto Dolcetti, Donato Pertici

摘要:

研究了非奇异对称实矩阵流形在迹度量下的微分几何性质,在正定矩阵的情况下,刻画了对称矩阵的完全群

英文摘要:

We study the differential geometric properties of the manifold of non-singular symmetric real matrices endowed with the trace metric; in case of positive definite matrices we describe the full group of isometries
