We develop an analytical method to prove congruences of the typek=0(pr1)/dAkzkω(z)k=0(pr11)/dAkzpk(modpmrZp[[z]])forr=1,2,, for primes p>2 and fixed integers m,d1, where f(z)=k=0Akzk is an ‘arithmetic’ hypergeometric series. Such congruences for m=d=1 were introduced by Dwork in 1969 as a tool for p-adic analytical continuation of f(z). Our proofs of several Dwork-type congruences corresponding to m2 (in other words, supercongruences) are based on constructing and proving their suitable q-analogues, which in turn have their own right for existence and potential for a q-deformation of modular forms and of cohomology groups of algebraic varieties. Our method follows the principles of creative microscoping introduced by us to tackle r=1 instances of such congruences; it is the first method capable of establishing the supercongruences of this type for general r.

通过创造性的q显微镜进行Dwork型超融合

我们开发一种分析方法来证明该类型的全等ķ=0p[R-1个/d一种ķžķωžķ=0p[R-1个-1个/d一种ķžpķp[Ržp[[ž]]对于[R=1个2 素数 p>2 和固定整数 d1个,在哪里 Fž=ķ=0一种ķžķ是“算术”超几何级数。这样的全等=d=1个是由Dwork在1969年引入的,它是p -adic分析连续性的工具Fž。我们证明了与Dwork型同余对应的2(换句话说,超同余)是基于构造和证明其合适的q类比的,它们反过来也具有存在的权利和潜力,可以模块化形式和代数变体的同调群进行q形变。我们的方法遵循我们引入的解决方案的创新性微观范围原理[R=1个这种一致性的实例;它是第一个能够为一般r建立这种超同余的方法。
