We use the Temperley-Lieb algebra to define a family of totally nonnegative polynomials of the form $$ \Sigma _{{\upsigma \in S_{n} }} f(\upsigma )x_{{1,\upsigma (1)}} \cdots x_{{n,\upsigma (n)}} $$. The cone generated by these polynomials contains all totally nonnegative polynomials of the form, where,are matrix minors. We also give new conditions on the setsI,...,K′ which characterize differences of products of minors which are totally nonnegative.
