简介：让G是一个有限的组。让Irr1(G)是G和cd1(G)的非线性的无法缩减的人物的集合在Irr1(G)的人物的度的集合。组G被说如果，是D2-group|cd1(G)|=|Irr1(G)|2。这份报纸的主要目的是分类nonsolvableD2-groups。

简介：如果X是一条弧或一个圆，那么，X上没有广泛的同胚，是众所周知的。在我们证明那的这篇论文，X上没有广泛的Z~d行动，它回答以前我们提出的二个问题。在1979，鬃毛证明在无限的维的空格没有广泛的同胚。与这结果相反，我们在一个无限的维的空格构造广泛的Z~2action。我们也在Z~2在零个维的空格而是没有元素构造一个广泛的Z~2行动是广泛的。

简介：让n≥2是一个固定积极整数，q≥3并且c是二个整数与(n，q)=(c，q)=1。我们由r表示n(δ1,δ2,c；q)(0<δ1,δ2≤1)都个整数的数字一，b令人满意的ab≡c(现代派的q)，1≤≤δ1q，1≤b≤δ2q，(一，q)=(b，q)=1并且n†(+b)。这篇论文的主要目的是学习rn(δ1,δ2,c；q)，并且为它给一个锋利的asymptotic公式。
