In mathematics, positive definiteness is a property of any object to which a bilinear form or a sesquilinear form may be naturally associated, which is positive-definite. See, in particular:

• Positive-definite bilinear form

• Positive-definite function

• Positive-definite function on a group

• Positive-definite functional

• Positive-definite kernel

• Positive-definite matrix

• Positive-definite operator

• Positive-definite quadratic form
