Abstract :
A positivity method for forms of even order is reported. It is shown that testing for positivity of such forms can be reduced to a test for positive definiteness of parametric-matrices. Special emphasis is placed on quartic- and sixth-order forms. Examples are given to illustrate the proposed criterion
