Modularity of Calabi--Yau varieties: 2011 and beyond
本文介绍了自2003年最后一次更新以来卡-丘品种模块化的现状。我们将集中讨论最多为3维的卡-丘簇。这里的模块性至少指两种不同的类型：算术模块性和几何模块性。这些措施包括：（1）模块化卡-丘簇的伽罗瓦表示的（自同构）（2）Calabi-Yau簇族的Picard-Fuchs微分方程解的模性和镜像映射（镜子月光），（3）模块化的生成函数的不变量计数一定数量的卡拉比-丘品种，（4）Calabi-Yau簇族模的模性。

Modularity of some non-rigid double octic Calabi-Yau threefolds
本文讨论了用$h^{12}=1$证明Calabi-Yau三重模性的四种方法：内部椭圆直纹曲面的存在性（Hulek-Verrill），与椭圆曲线和K3曲面的乘积的对应性（Livné-Yui），与（模）刚性Calabi-Yau三重模性的对应性，以及将四维表示分解为二维子表示的对合的存在性.我们应用这些方法来证明模块性的17个双octic卡-丘三倍，其中“模块性的数值证据”，发现在第二作者的论文。我们观察到，模块化持有铅笔中的那些元素有一些额外的几何属性。在证明中，我们使用所考虑的卡-丘三重作为库默尔纤维化的合理椭圆纤维化的纤维积的表示。
We exhibit three double octic Calabi--Yau threefolds over the certain quadratic fields and prove their modularity. The non-rigid threefold has two conjugate Hilbert modular forms of weight [4,2] and [2,4] attached while the two rigid threefolds correspond to a Hilbert modular form of weight [4,4] and to the twist of the restriction of a classical modular form of weight 4.

We discuss Calabi-Yau and fractional Calabi-Yau semiorthogonal components of derived categories of coherent sheaves on smooth projective varieties. The main result is a general construction of a fractional Calabi-Yau category from a rectangular Lefschetz decomposition and a spherical functor. We give many examples of application of this construction and discuss some general properties of Calabi-Yau categories.
Flux compactification of IIB string theory associates special points in Calabi-Yau moduli space to choices of (pairs of) integral three-form fluxes. In this paper, we propose that supersymmetric flux vacua are modular. That is, to a supersymmetric flux vacuum arising in a variety defined over $\mathbb{Q}$, we associate a two-dimensional Galois representation that we conjecture to be modular. We provide numerical evidence for our conjecture by examining flux vacua arising on the octic hypersurface in $\mathbb{P}^{4}(1,1,2,2,2)$.

In this survey, we discuss the state of art about the monodromy property for Calabi-Yau varieties.

In this note, an overview of Calabi-Yau varieties in positive characteristic is presented. Although Calabi-Yau varieties in characteristic zero are unobstructed, there are examples of Calabi-Yau threefolds in positive characteristic which cannot be lifted to characteristic zero, although one-dimensional and two-dimensional Calabi-Yau varieties, i.e., elliptic curves and K3 surfaces, are all liftable to characteristic zero. In this respect, Calabi-Yau threefolds in positive characteristic are interesting in view of deformation theory and they are still very mysterious.

It is known that a maximal intersection log canonical Calabi-Yau surface pair is crepant birational to a toric pair. This does not hold in higher dimension: this paper presents some examples of maximal intersection Calabi-Yau pairs that admit no toric model.
In this paper, we will construct new examples of derived equivalent Calabi--Yau 3-folds with Picard number greater than one. We also study their mirror Calabi--Yau manifolds and find that they are given by Schoen's fiber products of suitable rational elliptic modular surfaces.

In this note we construct conifold transitions between several Calabi-Yau threefolds given by Pfaffians in weighted projective spaces and Calabi-Yau threefolds appearing as complete intersections in toric varieties. We use the obtained results to predict mirrors following ideas of \cite{BCKS, Batsmalltoricdegen}. In particular we consider the family of Calabi--Yau threefolds of degree 25 in $\mathbb{P}^9$ obtained as a transverse intersection of two Grassmannians in their Plucker embeddings.
Primitive Calabi-Yau Threefolds
一个本原的卡-丘三重是一个非奇异的卡-丘三重，它不能写成卡-丘三重退化的奇异纤维的一个可破分解。这些应该被认为是最基本的卡-丘流形;所有其他的流形都应该通过这些流形的退化而产生。本文首先继续研究具有典型奇点的Calabi-Yau三折叠的光滑性，这是作者在前一篇论文中开始的。''（alg-geom 9506022）.若X'是非奇异的三重Calabi-Yau图，f：X'->X是一个因子到曲线的收缩，我们得到了X何时可光滑的结果.然后，我们讨论了这一结果的原始卡-丘三重分类的应用。将本文的形变理论结果与“形变Calabi-Yau三重”的结果相结合，得到了对本原Calabi-Yau三重类的强限制.我们还推测如何这样的工作可能会产生的结果连接在一起的所有模空间的卡-丘三倍。
