Title: Capped equivariant vertex with 2 legs

Abstract:

We derive an explicit formula for the capped vertex with 2 legs twisted by the bundles O ⊕ O(−1). Using this result we obtain a formula for the operator corresponding to horizontal legs of resolved conifold, and in particular prove its polynomiality in the Kahler variable.
