So, you must be careful to show that this equality holds as a set equality. In either case, det[A]≠0 must hold, that is 0 must not be an eigenvalue of the matrix A. Ah, I see. I guess the complex logarithm is a bit more troublesome than I thought! But then I think the...
Consequently, λ(i) is the eigenvector of the tensor of inertia directed along one of the principal axes: Iλ(i) = Iiλ(i). Using this and the relations (3.8), on the given level set of the angular momentum integral M = M 0 we find λx(i) = Mx0 , Ii + D λy(i) = My...
