Nutsa Gegelia, Duco van Straten
We construct certain special rational elliptic surfaces with four reduced singular fibres that are naturally attached to the platonic solids and belong to a group of surfaces compl…

Paramodular forms from Calabi-Yau Operators
Nutsa Gegelia, Duco van Straten
In this note we report on the conjectural identification of paramodular forms from Calabi-Yau motives of Hodge type (1, 1, 1, 1) of moderately low conductor. We calculate Euler fac…
