Abstract

A new concept of moderate non-locality in higher-spin gauge theory is introduced. Based on the recently proposed differential homotopy approach, a moderately non-local scheme, that issofter than those resulting from the shifted homotopy approach available in the literature so far, is worked out in the mixed ηη sector of the Vasiliev higher-spin theory. To calculate moderately non-local vertices Υ^{η η}(ω, C,C,C) for all ordering of the fields ω and C we apply an interpolating homotopy, that respects the moderate non-locality in the perturbative analysis of the higher-spin equations.
