举办意义(Significance)
Hodge 猜想属于代数几何的领域,在数学中的著名猜想,很多数学家比如Hodge、Grothendieck、Deligne、Bloch、Voisin等围绕这个猜想发展了系统的理论并且引申了新的问题。Hodge猜想预测一个有理系数的上同调类如果其Hodge型达到代数链的预期那么它对应代数链的上同调类。代数链通常认为是自然的几何对象,所以一个自然的延伸问题是什么样的对象来自几何(motivic)。对特征0上的代数簇,复数(有理数)作为系数反映的是一种局部,如果试图考虑更多的局部,在每个素数p处,我们将得到p-adic系数和特征p的域系数,此时有一个本质的现象是Frobenius作用,考虑上同调类在不同系数下的表示将让我们更全面地理解代数链,与此相关的理论是p-adic Hodge理论。
Higgs丛的周期性是一种反应几何性的新观点,它把各个系数联系起来,是研究Hodge猜想一种有潜力的工具。这次研讨会将围绕这种观点展开讨论,并且学习一些前置知识,包括复数域上经典的Hodge理论在p-adic的类比、不同系数的local system理论、Crystalline cohomology(在几何和数论中的应用)等等。通过这个研讨会,大家能够交流自己熟悉的知识,学习到基础的p-adic Hodge理论的知识,能够从新的角度看待Hodge猜想和几何对象,与此同时学习到一些相关问题并且讨论解决相关问题的可行的方案。这次研讨会的参与者都有自己的研究领域,包括双有理几何、Higgs丛、代数簇的拓扑等等,还有部分学生参与,这次研讨会将会地促进领域间的交流,消除一些技术壁垒,从而从整体上促进Hodge理论的发展。
