Thus, from Theorem 7, we see that (mathcal{A}) is positive definite, that is, (f(x)) is positive definite.
Thus, from Theorem 2.4, we can see that (mathcal{A}) is positive definite, that is, (f(x)) is positive definite.
Since A is positive definite, (H=(A+A^)/2) is Hermitian positive definite, that is, (x^Hx>0) for any (xneq0), (xinmathbb{C}^{n}).
If is (i) regular in [16]; (ii) positive definite, that is, for, and ; (iii) radially unbounded, that is, as, then is said to be C-regular.
If H is positive definite, that is, if (det H >0), then it is well known that (v^{T} H v >0) for all (vneq 0).
on, and it is positive definite, that is, Riemannian, if and only if satisfies on all (the graph is then said to be spacelike).
