On the Number of Mutually Touching Cylinders
In a three-dimensional arrangement of 25 congruent nonoverlapping infinite circular cylinders there are always two that do not touch each other.
متن کاملSymmetry, topology and the maximum number of mutually pairwise-touching infinite cylinders: configuration classification
We provide a complete classification of possible configurations of mutually pairwise-touching infinite cylinders in Euclidian three-dimensional space. It turns out that there is a maximum number of such cylinders possible in three dimensions independently of the shape of the cylinder cross-sections. We give the explanation of the uniqueness of the non-trivial configuration of seven equal mutual...
متن کاملAn improvement on the number of simplices in
Let E be a set of points in Fq . Bennett, Hart, Iosevich, Pakianathan, and Rudnev (2016) proved that if |E| qd− d−1 k+1 then E determines a positive proportion of all k-simplices. In this paper, we give an improvement of this result in the case when E is the Cartesian product of sets. Namely, we show that if E is the Cartesian product of sets and q kd k+1−1/d = o(|E|), the number of congruence ...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
