Polylogarithms on arbitrary higher-genus Riemann surfaces can be constructed from meromorphic integration kernels with at most simple poles, whose definition was given by Enriquez via functional properties. In this work, homotopy-invariant convolution integrals over homology cycles are shown to provide a direct construction of Enriquez kernels solely from holomorphic Abelian differentials and the prime form. Our new representation is used to demonstrate the closure of the space of Enriquez kernels under convolution over homology cycles and under variations of the moduli. The results of this work further strengthen the remarkable parallels of Enriquez kernels with the non-holomorphic modular tensors recently developed in an alternative construction of higher-genus polylogarithms.
