Abstract: The main theorem here is the Ktheoretic analogue of the cohomological "stable double component formula" for quiver polynomials in [KMS]. This Ktheoretic version is still in terms of lacing diagrams, but nonminimal diagrams contribute terms of higher degree. The motivating consequence is a conjecture of Buch [B1] on the sign alternation of the coefficients appearing in his expansion of quiver Kpolynomials in terms of stable Grothendieck polynomials for partitions.
