在一个非平凡的LCM-闭集上,至少有一半的数是相同的,那么这个非平凡的divisor呢?

Share at least half the numbers in a nontrivial LCM-closed set a nontrivial divisor?

Tom Fischer

摘要:

对于一个非零自然数的有限集,如果它包含至少一个不同于1的元素和它的任何子集的最小公倍数,则存在一个子集,它的至少一半成员的公因数大于1。利用自然数作为素幂集的序理论环的表示,证明了该猜想等价于Frankl的并闭集猜想.一些结果的情况下,猜想,这也有意义的解释图和格理论,是已知的举行。这个猜想的一个等价对偶版本是,对于一个包含至少两个元素和任意子集的最大公因数的非零自然数的有限集,其中一个成员的素幂不是超过一半成员的素幂。

英文摘要:

For a finite set of non-zero natural numbers that contains at least one element different from 1 and the least common multiple of any of its subsets, there exists a subset of at least half of its members which has a common divisor larger than 1. Utilizing a representation of the natural numbers as an order-theoretical ring of prime power sets, this conjecture is shown to be equivalent to Frankl's union-closed sets conjecture. Some results for cases where the conjecture, which also has meaningful interpretations in graph and lattice theory, is known to hold are provided. An equivalent dual version of the conjecture is, that for a finite set of non-zero natural numbers that contains at least two elements and the greatest common divisor of any of its subsets, one of its members has a prime power that is not a prime power of more than half of the members.
