     Our upper bound is the best possible, and it implies the existence of low-rank factorizations of positive semidefinite bivariate matrix polynomials and representations of biforms as sums of few squares.

2. (taxonomy) A taxonomic designation (such as of a subspecies) consisting of more than two terms.
3. (linguistics, Sinology) A type of term consisting of multiple parts. This term needs a definition. Please help out and add a definition, then remove the text {{rfdef}}.
