This set can also be viewed as the best containment region for the determinant of a square matrix X in terms of the singular values of its symmetric and skew-symmetric parts. The technique is extended to study the principal minors of X. Similar problems for real matrices are considered....

For small degrees of freedom, the chi-square distribution is: a) rectangular b) skewed to the right c) skewed to the left d) symmetric Which of the following is an example of perfect mulitcollinearity? a. When X_1i is equal to...
The compact case is also discussed. As applications, two unexpected singular values inequalities concerning the sum of two real matrices and the sum of two real skew symmetric matrices are obtained. 展开 关键词: eigenvalues singular values partial order DOI: 10.2307/119180 年份: 1998 ...
In Sect. 2 we consider [Math Processing Error]XA,k where [Math Processing Error]A is a subset of an arbitrary abelian group [Math Processing Error]G and identify [Math Processing Error]H~k−1(XA,k;F) with a certain subspace [Math Processing Error]H(A) of skew-symmetric elements of...
