A Group Action on Derangements
نویسندگان
چکیده
In this paper we define a cyclic analogue of the MFS-action on derangements, and give a combinatorial interpretation of the expansion of the n-th derangement polynomial on the basis {qk(1 + q)n−1−2k}, k = 0, 1, . . . , b(n− 1)/2c.

Levo-Carnitine Reduces Oxidative Stress and Improves Contractile Functions of Fast Muscles in Type 2 Diabetic Rats
Background: Metabolic derangements in type 2 diabetes mellitus (T2DM) are likely to affect skeletal muscle contractile functions adversely. Levo-carnitine improves muscle contractile functions in healthy humans and rats and corrects metabolic derangements in T2DM. Therefore, it is likely to improve muscle contractile functions in T2DM as well. This study was designed to determine the effect of ...
متن کاملCyclic Derangements
A classic problem in enumerative combinatorics is to count the number of derangements, that is, permutations with no fixed point. Inspired by a recent generalization to facet derangements of the hypercube by Gordon and McMahon, we generalize this problem to enumerating derangements in the wreath product of any finite cyclic group with the symmetric group. We also give qand (q, t)-analogs for cy...
متن کاملOn Parallel Generation of Partial Derangements, Derangements and Permutations
The concept of a partial derangement is introduced and a versatile representation of partial derangements is proposed with permutations and derangements as special cases. The representation is derived from a representation of permutations by iterative decomposition of symmetric permutation group Sn into cosets. New algorithms are proposed for generation of partial set derangements in t. The con...

متن کاملP-207: Deltamethrin-Induced Derangements Correlates with Estrogen Synthesis, Angiogenesis and Oxidative Stress
Background: Deltamethrin (DTM) is a pyrethroid derivative, which is the most potent products of Type 2 insecticides and acts by delaying the closure of sodium channels. Estrogen as a vascular growth factor on ovarian tissue plays an essential impact further to its involvement in follicular growth. On the other hand, the role of angiogenesis on ovarian tissue in inhibiting the apoptotic provoker...
