%0 Journal Article %T Frobenius polynomials for Calabi-Yau equations %A Kira Samol %A Duco van Straten %J Mathematics %D 2008 %I arXiv %X We describe a variation of Dworks unit-root method to determine the degree four Frobenius polynomial for members of a 1-modulus Calabi-Yau family over $\mathbb{P}^1$ in terms of the holomorphic period near a point of maximal unipotent monodromy. The method is illustrated on a couple of examples. %U http://arxiv.org/abs/0802.3994v3
