Abstract
Let [InlineEquation not available: see fulltext.] be such that [InlineEquation not available: see fulltext.] and [Equation not available: see fulltext.] Then [Equation not available: see fulltext.] This can also be stated in terms of real positive definite [InlineEquation not available: see fulltext.]-matrices [InlineEquation not available: see fulltext.], [InlineEquation not available: see fulltext.]: If their determinants are equal, [InlineEquation not available: see fulltext.], then [Equation not available: see fulltext.] where log is the principal matrix logarithm and [InlineEquation not available: see fulltext.] denotes the Frobenius matrix norm. Applications in matrix analysis and nonlinear elasticity are indicated. MSC: 26D05, 26D07.
