We discuss some algebraic and analytic properties of a general class of orthogonal polyanalyticpolynomials, including their operational formulas, recurrence relations, generating functions, integral representations and different orthogonality identities. We establish their connection and rule in describing the L-2-spectral theory of some special second order differential operators of Laplacian type acting on the L-2-Gaussian Hilbert space on the whole complex plane. We will also show their importance in the theory of the so-called rank-one automorphic functions on the complex plane. In fact, a variant subclass leads to an orthogonal basis of the corresponding L-2-Gaussian Hilbert space on the strip C/Z.
