Theta functions on the bounded symmetric domain of type \(I_{2,2}\) and the period map of a 4-parameter family of K3 surfaces
The inverse of the period map of the 4-dimensional family of K3 surfaces, the double covers of \(\mathbb{P}^ 2\) branching along six lines, is expressed by theta functions on the symmetric domain of type \(I_{2,2}\).
