Query: The 2-leg vertex in K-theoretic DT theory   K-theoretic Donaldson-Thomas counts of curves in toric and many related
threefolds can be computed in terms of a certain canonical 3-valent tensor, the
K-theoretic equivariant vertex. In this paper we derive a formula for the
vertex in the case when two out of three entries are nontrivial. We also
discuss some applications of this result.
