Based on the screened vertex operators associated with the affine screening operators, we introduce the formal power serieswhich we call thenon-stationary Ruijsenaars function. We identify it with the generating function for the Euler characteristics of the affine Laumon spaces. When the parametersandare suitably chosen, the limitofgives us the dominant integrable characters ofmultiplied by(i.e.thecharacter). Several conjectures are presented for, including the bispectral and the Poincaré dualities, and the evaluation formula. The main conjecture asserts that (i) one can normalizein such a way that the limitexists, and (ii) the limitgives us the eigenfunction of the elliptic Ruijsenaars operator. The non-stationary affine-difference Toda operatoris introduced, which comes as an outcome of the study of the Poincaré duality conjecture in the affine Toda limit. The main conjecture is examined also in the limiting cases of the affine-difference Toda (), and the elliptic Calogero–Sutherland () equations.
