Does this encompass all positive-definite matrices? The Mathworld page leads me to believe that there are positive-definite matrices that are not Hermitian...

I would appreciate a link to a more detailed explanation of the "positive definite kernel" concept, with illustrations instead of only those theoretical...

following points are lacking: the related notion of positive definite matrix; the matrix of a definite quadratic form and the characterization of the positiveness...

There seems to be confusion about positive semi-definite versus positive definite. Sam Coskey 03:02, 6 December 2006 (UTC) yeah, it's rather unfortunate...

related and neither can be referred to by the title of the page. "Positive definiteness" is a single concept which is common to all the different areas...

The introduction says a positive-definite function on a group relates the notions of positivity, in the context of Hilbert spaces, and algebraic groups...

term "positive definite" has been introduced primarily for quadratic forms. Therefore it is a pity to have two different articles for Definite bilinear...

adjointness is mentioned in the introduction, the paragraph "Positive and positive definite operators" begins like a new definition, also introduces a new...

think the usual definition of positive is that c 1 ( L ) {\displaystyle c_{1}(L)} is represented by a positive definite, ie Kähler form ω {\displaystyle...

symmetric or Hermitian ? A is positive definite, and all positive-definite matrices are Hermitian (see positive-definite matrix). I hope this concise explanation...

Just mention the covariance matrix. If someone knows what 'positive definite' means they will be able to understand a covariance matrix. This distinction...

a positive definite real vector space, that is determined by the set S of its minimal vectors in the sense that there is only one positive definite quadratic...

(talk) 17:54, 8 December 2007 (UTC) Should it be positive semidefinite matrices instead of positive definite matrices? — Preceding unsigned comment added...

redirecting to different contradictory meanings. I'm making it redirect to positive definite kernels, because this is the correct usage given what links here:...

_{j}\not =0} , so by continuity either positive definite or negative definite, not the claimed "iff positive definite" of this page. That seems to make sense...

non-symmetric matrices as well. Can I conclude that a non-symmetric matrix is positive definite if the Sylvester's criterion is satisfied? How does the Sylvester...

that if a positive definite quadratic form with integer matrix represents all positive integers up to 15, then it represents all positive integers. I'm...

Maybe redirect the positive definite link to Positive-definite matrix ? elpincha 16:08, 16 Feb 2005 (UTC) Go for it. Charles Matthews 19:01, 16 Feb 2005...

(see definition in the “geometrical properties” section) is strictly positive-definite everywhere on S. I haven't read the reference yet, but it doesn't...
