Canonical labeling of a graph consists of assigning a unique label to each vertex such that the labels are invariant under isomorphism. Such a labeling can be used to solve the graph isomorphism problem. We give a simple, linear time, high probability algorithm for the canonical labeling of a G(n, p) random graph for p ∈ [ ω ( ln n/n ln lnn ) , 1− ω ( ln(More)
Acquired pure red cell aplasia is rare disorder of hematopoiesis. Because of the variety of reasons for PRCA optimal treatment is based on highly specialistic diagnostics. Both humoral and cellular mechanisms are involved in the pathogenesis of PRCA. Corticosteroids, cyclosporin A, high-dose intravenous immunoglobulin therapy are recommended in PRCA.(More)
