On the number of shredders

نویسنده

  • Tibor Jordán
چکیده

A subset S of k vertices in a k-connected graph G is a shredder if G ?S has at least three components. We show that if G has n vertices then the number of shredders is at most n, which was conjectured by Cheriyan and Thurimella 1]. If G contains no meshing shredders (in particular if k 3), the sharp upper bound b(n ? k ? 1)=2c is proven.

For a graph G, a subset S of V (G) is called a shredder if G− S consists of three or more components. We show that if G is a 10-connected graph of order at least 4227, then the number of shredders of cardinality 10 of G is less than or equal to (2|V (G)| − 11)/3.

(t, k)-Shredders in k-Connected Graphs

Let t, k be integers with t ≥ 3 and k ≥ 1. For a graph G, a subset S of V (G) with cardinality k is called a (t, k)-shredder if G−S consists of t or more components. In this paper, we show that if t ≥ 3, 2(t−1) ≤ k ≤ 3t−5 and G is a k-connected graph of order at least k, then the number of (t, k)-shredders of G is less than or equal to ((2t−1)(|V (G)|−f(|V (G)|)))/(2(t−1)), where f(n) denotes t...
