Calabi-Yau threefolds of type K (I): Classification
Kenji Hashimoto, Atsushi Kanazawa
Any Calabi-Yau threefold X with infinite fundamental group admits an étale Galois covering either by an abelian threefold or by the product of a K3 surface and an elliptic curve. W…

The ring of modular forms for the even unimodular lattice of signature (2,10)
Kenji Hashimoto, Kazushi Ueda
We show that the ring of modular forms with characters for the even unimodular lattice of signature (2,10) is generated by forms of weights 4, 10, 12, 16, 18, 22, 24, 28, 30, 36, 4…

Modular surfaces associated with toric K3 hypersurfaces
Kenji Hashimoto, Atsuhira Nagano, Kazushi Ueda
We give detailed descriptions of the period maps of two 2-parameter families of anti-canonical hypersurfaces in toric 3-folds. One of them is related to a Hilbert modular surface,…
