Mirror symmetry for Pfaffian Calabi-Yau 3-folds via conifold transitions (1310.2304v2)
Published 8 Oct 2013 in math.AG
Abstract: In this note we construct conifold transitions between several Calabi-Yau threefolds given by Pfaffians in weighted projective spaces and Calabi-Yau threefolds appearing as complete intersections in toric varieties. We use the obtained results to predict mirrors following ideas of \cite{BCKS, Batsmalltoricdegen}. In particular we consider the family of Calabi--Yau threefolds of degree 25 in $\mathbb{P}9$ obtained as a transverse intersection of two Grassmannians in their Plucker embeddings.
