2.11

A supercurrent on UU is a continuous linear functional on Acp,q​(U)A_{c}^{p,q}(U) where the latter is a locally convex vector space in a similar way as in the classical case. We denote the space of such supercurrents by Dp,q​(U)D_{p,q}(U). As usual, we define the linear differential operators dd, d′d^{\prime} and d′′d^{\prime\prime} on D⁡(U):=⨁p,qDp,q​(U)D(U):=\bigoplus_{p,q}D_{p,q}(U) by using (−1)p+q+1(-1)^{p+q+1} times the dual of the corresponding differential operator on Acp,q​(U)A_{c}^{p,q}(U). The sign is chosen in such a way that the canonical embedding Ap,q​(U)→Dr−p,r−q​(U)A^{p,q}(U)\rightarrow D_{r-p,r-q}(U) is compatible with the operators dd, d′d^{\prime} and d′′d^{\prime\prime}. Here, α∈Ap,q​(U)\alpha\in A^{p,q}(U) is mapped to [α]∈Dr−p,r−q​(U)[\alpha]\in D_{r-p,r-q}(U) given by [α]​(β)=∫Nℝα∧β[\alpha](\beta)=\int_{N_{\mathbb{R}}}\alpha\wedge\beta for any β∈Acr−p,r−q​(U)\beta\in A_{c}^{r-p,r-q}(U).
