Examples of Matrix Factorizations from SYZ    [PDF]

Cheol-Hyun Cho, Hansol Hong, Sangwook Lee

We find matrix factorization corresponding to an anti-diagonal in $\CP^1 \times \CP^1$, and circle fibers in weighted projective lines using the idea of Chan and Leung of Strominger-Yau-Zaslow transformations. For the tear drop orbifolds, we apply this idea to find matrix factorizations for two types of potential, the usual Hori-Vafa potential or the bulk deformed (orbi)-potential. We also show that the direct sum of anti-diagonal with its shift, is equivalent to the direct sum of central torus fibers with holonomy $(1,-1)$ and $(-1,1)$ in the Fukaya category of $\CP^1 \times \CP^1$, which was predicted by Kapustin and Li from B-model calculations.
