Abstract

Let XX be a compact, K\"ahler, Calabi-Yau threefold and suppose XXXtX\mapsto \underline{X}\leadsto X_t , for tΔt\in \Delta, is a conifold transition obtained by contracting finitely many disjoint (1,1)(-1,-1) curves in XX and then smoothing the resulting ordinary double point singularities. We show that, for t1|t|\ll 1 sufficiently small, the tangent bundle T1,0XtT^{1,0}X_{t} admits a Hermitian-Yang-Mills metric HtH_t with respect to the conformally balanced metrics constructed by Fu-Li-Yau. Furthermore, we describe the behavior of HtH_t near the vanishing cycles of XtX_t as t0t\rightarrow 0.
