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 quadratic form
