The moduli space of stable bundles on a Riemann surface possesses a natural family of holomorphic trivector fields. Some explicit examples were given in my talk at ICMAT in September. This lecture is an attempt to understand a role for these in the Hochschild cohomology of the moduli space and its relationship with the cohomology of polyvector fields.
