Large highly connected subgraphs in graphs with linear average degree

Combinatorics 2020-03-03 v1

Abstract

In 1972 Mader proved that every graph with average degree at least 4k4k has a (k+1)(k+1)-connected subgraph with more than 2k2k vertices. We improve this bound by showing that the constant 44 can be replaced by 3+133+\frac{1}{3}; this bound is sharp.
