Novoseltsev %A Alan Thompson %J Mathematics %D 2015 %I arXiv %X We study threefolds fibred by mirror quartic K3 surfaces. We begin by showing that any family of such K3 surfaces is completely determined by a map from the base of the family to the moduli space of mirror quartic K3 surfaces. This is then used to give a complete explicit description of all Calabi-Yau threefolds fibred by mirror quartic K3 surfaces. We conclude by studying the properties of such Calabi-Yau threefolds, including their Hodge numbers, deformation theory, and candidate mirror partners. %U http://arxiv.org/abs/1501.04019v1
