Dolbeault Complex on S^4\{.} and S^6\{.} through Supersymmetric Glasses (1105.3935v3)

Abstract: S^4 is not a complex manifold, but it is sufficient to remove one point to make it complex. Using supersymmetry methods, we show that the Dolbeault complex (involving the holomorphic exterior derivative and its Hermitian conjugate) can be perfectly well defined in this case. We calculate the spectrum of the Dolbeault Laplacian. It involves 3 bosonic zero modes such that the Dolbeault index on S^4{.} is equal to 3.
