Multi-Quasi-Elliptic Operators in ℝn
Multi-quasi-elliptic polynomials p(ζ), (ζ) ∈ ℝd,are important examples in the class of the hypoelliptic polynomials of Hormander [12]; they contain as particular cases the elliptic and quasi-elliptic polynomials, as well as any product of polynomials of this type. Their detailed study was carried out in the years 1960–70 by Cattabriga [7], Pini [17], Volevic-Gindikin [20], Friberg [8] and others.
