On the Number of Permutations Admitting an m-th Root

نویسنده

  • Nicolas Pouyanne
چکیده

Let m be a positive integer, and pn(m) the proportion of permutations of the symmetric group Sn that admit an m-th root. Calculating the exponential generating function of these permutations, we show the following asymptotic formula pn(m) ∼ n→+∞ πm n1−φ(m)/m , where φ is the Euler function and πm an explicit constant.

Sharply $(n-2)$-transitive Sets of Permutations

Let $S_n$ be the symmetric group on the set $[n]={1, 2, ldots, n}$. For $gin S_n$ let $fix(g)$ denote the number of fixed points of $g$. A subset $S$ of $S_n$ is called $t$-emph{transitive} if for any two $t$-tuples $(x_1,x_2,ldots,x_t)$ and $(y_1,y_2,ldots ,y_t)$ of distinct elements of $[n]$, there exists $gin S$ such that $x_{i}^g=y_{i}$ for any $1leq ileq t$ and additionally $S$ is called e...

Reaction of Different Pepper Cultivars to Two Species of Root- Knot Nematodes (M. Javanica and M. Incognita)

Root knot nematode is one of the important plant pathogens that causes damage to many crops, including greenhouse crops. Pepper is an agricultural crop which its cultivation has increased in recent years, especially in greenhouses. Most of the adopted management methods for this nematode have not met the required efficiency. In this study, reaction of some pepper cultivars (Elmina, Tuvana, Chal...

Computation of the q-th roots of circulant matrices

In this paper, we investigate the reduced form of circulant matrices and we show that the problem of computing the q-th roots of a nonsingular circulant matrix A can be reduced to that of computing the q-th roots of two half size matrices B - C and B + C.
