Abstract
To any Frobenius superalgebra we associate towers of Frobenius nilCoxeter algebras and Frobenius nilHecke algebras. These act naturally, via Frobenius divided difference operators, on Frobenius polynomial algebras. When is the ground ring, our algebras recover the classical nilCoxeter and nilHecke algebras. When is the two-dimensional Clifford algebra, they are Morita equivalent to the odd nilCoxeter and odd nilHecke algebras.
