The existence of (v, 4, λ) disjoint difference families
A (v, k, λ) difference family ((v, k, λ)-DF in short) over an abelian group G of order v is a collection F = {Bi | i ∈ I} of k-subsets of G, called base blocks, such that each nonzero element of G can be represented in precisely λ ways as a difference of two elements lying in some base blocks in F . A disjoint (v, k, λ)-DF is a difference family with disjoint blocks. In this paper, it is proved...
متن کاملStates with v 1 = λ , v 2 = − λ and reciprocal equations in the six - vertex model
States with v 1 = λ, v 2 = −λ and reciprocal equations in the six-vertex model Abstract The eigenvalues of the transfer matrix in a six-vertex model (with periodic boundary conditions) can be written in terms of n constants v 1 ,. .. , v n , the zeros of the function Q(v). A peculiar class of eigenvalues are those in which two of the constants v 1 , v 2 are equal to λ, −λ , with ∆ = − cosh λ an...
متن کاملA comparison of R. v. Stone with R. v. Parks: two cases of automatism.
Both the medical and legal professions recognize that some criminal actions take place in the absence of consciousness and intent, thereby inferring that these actions are less culpable. However, experts enter a legal quagmire when medical expert evidence attempts to find some common meaning for the terms “automatism” and “unconsciousness.” The Concise Oxford Dictionary defines automatism as “I...
متن کاملFACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY
Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...
متن کاملProper edge coloring of BIBD(v, 4, λ)s
A decomposition of λ copies of monochromatic Kv into copies of K4 such that each copy of K4 contains at most one edge from each Kv is called a proper edge coloring of a BIBD(v, 4, λ). We show that the necessary conditions are sufficient for the existence of a BIBD(v, 4, λ) which has such a proper edge coloring.
