    Using the finite temperature (Matsubara) Green's function method, the hole spectral function is calculated in a representation where holes are described as spinless fermions (holons) and spins as normal bosons. The holon self-energy term for multiple spin-wave processes is analytically determined with the spin polaron Hamiltonian as the interaction term in the S-matrix. The usual prescription of analytic continuation then enables us to obtain the retarded expression from the Matsubara self-energy term yielding the holon spectral function.
