Well maybe that's not absolutely definite, writes Andy Wilson.
An Hermitian matrix A is said to be positive semi-definite or nonnegative definite, written as A ≥ 0, if x ∗ A x ≥ 0, ∀ x ∈ C n.
A Hermitian matrix is said to be positive semidefinite or nonnegative definite, written as, if (1.1). is further called positive definite, symbolized, if the strict inequality in (1.1) holds for all nonzero.
A matrix (Sin {mathbb{R}}_{s}^{ntimes n}) is said to be positive definite (resp. semipositive definite), written as (S> 0) (resp. (S geq 0)), if (y^{T}Sy> 0) (resp. (y^{T}Sygeq0)) for any (yin{ mathbb{R}}^{n}) with (yneq0).
A Hermitian matrix is said to be positive semidefinite or nonnegative definite, written as, if (see, e. g., [2], p.159) (1.2). is further called positive definite, symbolized, if the strict inequality in (1.2) holds for all nonzero.
An Hermitian matrix A is said to be positive semidefinite or nonnegative definite, written as A ≥ 0, if (see, e.g., [[1], p. 159]) x H A x ≥ 0, ∀ x ∈ ℂ n, (1.2).
"The answer is a definite no," wrote David Fulghum, one of the reporters who wrote the article cited at the top of this post.
Grierson recalled after the war that Hurlbut gave him only verbal orders because Hurlbut considered the mission too dangerous and doubtful "to take the responsibility to give definite or written orders for its execution".
