His Cronica is viewed as the first introduction of statistics as a positive element in history. However, historian Kenneth R. Bartlett notes that, in contrast...

positive linear functional ω on a *-algebra A is said to be faithful if, for any positive element a in A, ω(a) = 0 implies that a = 0. Every element Ω...

positive element a is invertible, then Her(a) = A. This suggests the following notion for the non-unital case: a ∈ A is said to be strictly positive if...

negative element corrects for chromatic aberration; the positive element facing the object is made of crown glass, while the negative element facing the...

general, a C*-algebra A is σ-unital if and only if A contains a strictly positive element, i.e. there exists h in A+ such that the hereditary C*-subalgebra generated...
