| Research Abstract |
We studied Hessian K3 surfaces of cubic surfaces of non-Sylvester types. They are obtained also as toric hypersurfaces, and considered as a mirror family of(2, 2, 2)-hypersurfaces of(P^1)^3. Their period integrals satisfy the Lauricella's hypergeometeric differential equations F_C, and the period domain is the Siegel upper half space of degree two.
