I was wondering whether the following commuting diagram property was enough to characterize the exterior derivative (although I'm suspicious. Is this answered somewhere in the literature? my question came about after posting a comment in What is the exterior derivative intuitively?)
Let $f$ be any smooth map $f:M\to N$ where $M$ and $N$ are smooth manifold and consider the map $f^*: A(N)\to A(M)$ between the spaces of smooth sections of the exterior form bundles $\Omega(N^*)$ and $\Omega(M^*)$, $A(N)$ and $A(M)$, associated to the manifolds $N$ and $M$. Then the exterior derivative is the unique map $d$ such that the following diagram commutes (and its properties follow from this characterization):
$\require{AMScd}$ \begin{CD} A(N) @>d>> A(N)\\ @V f^* V V @VV f^* V\\ A(M)@>>d> A(M) \end{CD}
Thanks.
