Let \(k\) and \(j\) be positive integers. We prove that the action of the two-dimensional singular integral operators \((S_\Omega )^{j-1}\) and \((S_\Omega ^*)^{j-1}\) on a Hilbert base for the Bergman space \(\mathcal{A }^2(\Omega )\) and anti-Bergman space \(\mathcal{A }^2_{-1}(\Omega ),\) respectively, gives Hilbert bases \(\{ \psi _{\pm j , k } \}_{ k }\) for the true poly-Bergman spaces \(\mathcal{A }_{(\pm j)}^2(\Omega ),\) where \(S_\Omega \) denotes the compression of the Beurling transform to the Lebesgue space \(L^2(\Omega , dA).\) The functions \(\psi _{\pm j,k}\) will be explicitly represented in terms of the \((2,1)\)-hypergeometric polynomials as well as by formulas of Rodrigues type. We prove explicit representations for the true poly-Bergman kernels and more transparent representations for the poly-Bergman kernels of \(\Omega \). We establish Rodrigues type formulas for the poly-Bergman kernels of \(\mathbb{D }\).
