We introduce and study wheeled PROPs, an extension of the theory of PROPs which can treat traces and, in particular, solutions to the master equations which involve divergence operators. We construct a dg free wheeled PROP whose representations are in one-to-one correspondence with formal germs of SP-manifolds, key geometric objects in the theory of Batalin-Vilkovisky quantization. We also construct minimal wheeled resolutions If classical operads Corn and Ass as non-trivial extensions of the well-known dg operads Com(infinity) and Ass(infinity). Finally, we apply the above results to a computation of cohomology of a directed version of Kontsevich's complex of ribbon graphs.
