... infinity, we often drop n from the notation. the electronic journal of combinatorics 15 (2008), #R29 7 Dominating sets of random 2-in 2-out directed graphs Stephen Howe ∗ Department of Mathematics ... base 1/(1 − p). Then the minimum size of a dominating set of a random digraph G ∈ DG n,p is a.a.s. k + 1 or k + 2. We study dominating sets in random 2-in 2-out...

... G  and B = E ∪ F ∪ G. The rank 2 flats of M (F 4 ) We will analyze the set of all matroid automorphisms of M(F 4 ) by concentrating on its rank 2 flats. The proof of the next proposition is straightforward. Proposition ... 4.6(3) of [4]. 2. By part (1), we have H 3 ∼ = H 2  H 1 , the subgroups of Lemmas 3.2 and 3.3. We will show that conjugation of any element of H 3 remains i...

... is any one of these types of tableaux, we shall let sh(T) = λ denote the shape of T , pos(T) denote the number of positive letters in the range of T and neg(T ) denote the number of negative ... numbers past the positive numbers as was done in [30, 31]. Another proof of the independence of the RHS of (31) of the relative order of the positive and negative letters can be...

... collected 610 terms in total; the average number of output terms per input is 12.2 terms. We checked whether each of the 610 terms is a correct related term of the original seed term by hand. The result ... (20%) out of 210 terms were col- lected by the system. This low recall primarily comes from the failure of automatic term recogni- tion (case A in the above classification). Impro...
