Abstract

The purpose of this paper is to prove a Pieri-type multiplication formula for quantum Grothendieck polynomials, which was conjectured by Lenart-Maeno. This formula would enable us to compute explicitly the quantum product of two arbitrary (opposite) Schubert classes in the (small) quantum KK-theory ring QK(Fln)QK(Fl_{n}) of the (full) flag manifold FlnFl_{n} of type An1A_{n-1} on the basis of the fact that quantum Grothendieck polynomials represent (opposite) Schubert classes in QK(Fln)QK(Fl_{n}).
