Green’s functions of the edh operators
J. Ivancovich, Carlos N. Kozameh, Ezra Ted Newman · Journal of Mathematical Physics · 1989
The spin-weight s Green’s functions for the operator ð and powers of ð are obtained. The extension of these Green’s functions to negative values of s and to the ð̄n operators, as well as a procedure for obtaining the Green’s function for any combination of products of ðn and ð̄n, is also given.
