Abstract
The principles of a multivariable polynomial nonnegativity test, which has applications in several system theory problems, are discussed. Basically, the (n - 1)-vaxiable nonnegativity test problem is transformed into one which forms a subclass of the n-variable positivity test problem. The added details ate illustrated through a nontrivial example.Keywords
