For Calabi—Yau threefolds with two dimensional moduli, it is still unknown how to determine the holomorphic anomalies arising from solving the BCOV recursion equations. In this talk I will discuss the example on abelian fibered CY3 studied by Hosono and Takagi recently, and try to understand the problem from the mirror side via GLSM with fibered LG phases.
