Source abstract

Let XX be a toric Fano surface. Let π:X^Xπ: \widehat{X} \rightarrow X be a toric blow up at a point. We use the Topological Vertex [AKMV] to prove a higher genus, higher winding, open-closed duality between the toric Calabi-Yau 3-folds KX,KX^K_X, K_{\widehat{X}}. For g0,w1g \geq 0, w \geq 1, we show the equality ng(KX^,πβwC)=(1)gNg,(w)LMOV(KX/L,β)n_g(K_{\widehat{X}}, π^*β- wC) = (-1)^g N_{g, (w)}^{LMOV}(K_X/L, β), where ng(KX^,πβwC)n_g(K_{\widehat{X}}, π^*β- wC) is the genus-gg, Gopakumar-Vafa invariant of KX^K_{\widehat{X}} in curve class πβwCπ^*β-wC, where βH2(X,Z)β\in H_2(X, \mathbb{Z}) and CC is the exceptional curve, and Ng,(w)LMOV(KX/L,β)N_{g, (w)}^{LMOV}(K_X/L, β) is the genus-gg, LMOV invariant of an outer Aganagic-Vafa brane LKXL \subset K_X in class ββ and representation (w)(w), or the Young Tableau of a single row with ww boxes.
