The set of cycle lengths of almost all permutations in Sn are "Poisson distributed": we show that this remains true even when we restrict the number of cycles in the per...
For a directed graph G without loops or parallel edges, let (G) denote the size of the smallest feedback arc set, i.e., the smallest subset X E(G) such that G \ X has no directed...
We prove that for every c > 0 there exists a constant K = K(c) such that every graph G with n vertices and minimum degree at least cn contains a cycle of length t for every even...
This paper aims at exploring the role of the product generation life cycle (PGLC) on differences in innovation strategy among industries in a crossindustry study of ten multinatio...
Thomassen [9] conjectured that for all natural numbers k > 0 and m, every graph of minimum degree k + 1 contains a cycle of length congruent to 2m modulo k. We prove that this ...
