Webbimodules B that would allow a viable cohomology theory for the II1 factors M, more generally for tracial von Neumann algebras M. A first priority for us was that the 1-cohomology with coefficients in B should not always vanish, i.e, that there should exist non-inner derivations of M into B, especially in the case M = LΓ with β(2) 1 (Γ) 6= 0, WebJun 24, 2024 · We review the gauge and ghost cyle graph complexes as defined by Kreimer, Sars and van Suijlekom in “Quantization of gauge fields, graph polynomials and graph homology” and compute their cohomology. These complexes are generated by labelings on the edges or cycles of graphs and the differentials act by exchanging these …
