On the possible volume of $mu$-$(v,k,t)$ trades
A $mu$-way $(v,k,t)$ $trade$ of volume $m$ consists of $mu$ disjoint collections $T_1$, $T_2, dots T_{mu}$, each of $m$ blocks, such that for every $t$-subset of $v$-set $V$ the number of blocks containing this t-subset is the same in each $T_i (1leq i leq mu)$. In other words any pair of collections ${T_i,T_j}$, $1leq i< j leq mu$ is a $(v,k,t)$ trade of volume $m$. In th...
متن کاملOn spanning trees and k-connectedness in infinite graphs
If two rays P,Q ⊂ G satisfy (i)–(iii), we call them end-equivalent in G. An end of G is an equivalence class under this relation, and E(G) denotes the set of ends of G. For example, the 2-way infinite ladder has two ends, the infinite grid Z×Z and every infinite complete graph have one end, and the dyadic tree has 20 ends. This paper is concerned with the relationship between the ends of a conn...

متن کاملSufficient degree conditions for k-edge-connectedness of a graph
One of Frank Boesch’s best known papers is ‘The strongest monotone degree conditions for n-connectedness of a graph’ [1]. In this paper, we give a simple sufficient degree condition for a graph to be k-edge-connected, and also give the strongest monotone condition for a graph to be 2-edge-connected.
