Abstract

Let XX be a smooth projective complex variety and let D=D1++DlD=D_1+\cdots+D_l be a reduced normal crossing divisor on XX with each component DjD_j smooth, irreducible, and nef. The log-local principle of van Garrel-Graber-Ruddat conjectures that the genus 0 log Gromov-Witten theory of maximal tangency of (X,D)(X,D) is equivalent to the genus 0 local Gromov-Witten theory of XX twisted by j=1lO(Dj)\bigoplus_{j=1}^l\mathcal{O}(-D_j). We prove that an extension of the log-local principle holds for XX a (not necessarily smooth) Q\mathbb{Q}-factorial projective toric variety, DD the toric boundary, and descendent point insertions.
