... difficult to see that the polynomials P X,Y,Z n (x) are related to some special cases of hit the electronic journal of combinat orics 13 (2006), #R64 38 Classifying Descents According to Equivalence mod ... increase the number of descents. Since σ  ends with a number which is not equivalent to k mod 0, σ c has n − j descents. If σ  = A1B(kn + k − 1), where A and B are som...

... electronic journal of combinatorics 7 (2000), #N4 2 Theorem 1 For any graphs G and H, γ(G)γ(H) ≤ 2γ(G  H). Proof. Let D be a dominating set of G  H. It is sufficient to show that γ(G)γ(H) ≤ 2|D|. ... = u i or u is adjacent to u i . This partition of V (G) induces a partition {D 1 ,D 2 , ,D γ(G) } of D where D i =(Π i × V (H)) ∩ D. Let P i be the projection of D i onto H.Thatis, P i = {v |...

It is easy to see that the initial situations that will lead to these descents are those with 1 (weakly) to the right of 2 which is to the right of 3, ... − q) ≤ 10(1 − q)/9. According to Theorem 2.1 we have three terms to bound (the last one is already constant, −1). We will first show that the third term (corresponding to desc...
