This is the tensor product of complex-valued functions on , acted on by , and anticommuting functions on , acted on by . The mutually adjoint operators square to zero. Mathematicians recognize this space as the complex differential forms , where the degree ranges from (functions) to . The de Rham differential squares to zero. The Euclidean inner product induces a Hermitian inner product on forms by integration; the adjoint of also squares to zero. The Laplacian operator on differential forms is
