K3 surfaces from configurations of six lines in ${\mathbb{P}}^2$ and mirror symmetry II --- ${\lambda }_{K3}$-functions ---

Shinobu Hosono, Bong Lian, Shing-Tung Yau

We continue our study on the hypergeometric system $E(3,6)$ which describes period integrals of the double cover family of K3 surfaces. Near certain special boundary points in the…
