Weakly Nonnegative Quadratic Forms,nd . positive roots of ., which can be used to characterize weak nonnegativity. We also describe . semi-unit forms, those forms not weakly nonnegative such that any proper restriction is weakly nonnegative. Diverse criteria for weak nonnegativity are provided, including Zeldych’s Theorem and a few a
