Letbe positive integers, and letbe a list ofvariables. TheBoolean product polynomialis the product of the linear forms, whereranges over all-element subsets of. We prove that Boolean product polynomials are Schur positive. We do this via a new method of proving Schur positivity using vector bundles and a symmetric function operation we callChern plethysm. This gives a geometric method for producing a vast array of Schur positive polynomials whose Schur positivity lacks (at present) a combinatorial or representation theoretic proof. We relate the polynomialsfor certainto other combinatorial objects including derangements, positroids, alternating sign matrices, and reverse flagged fillings of a partition shape. We also relateto a bigraded action of the symmetric groupon a divergence free quotient of superspace.
