Spectral approaches for $d$ -improper chromatic number

Krystal Guo, Ross J. Kang, Gabriëlle Zwaneveld

In this paper, we explore algebraic approaches to $d$ -improper and $t$ -clustered colourings, where the colouring constraints are relaxed to allow some monochromatic edges. Bilu [J.…

Reconfiguration of Independent Transversals

Pjotr Buys, Ross J. Kang, Kenta Ozeki

Given integers $Δ \geq 2$ and $t \geq 2Δ$ , suppose there is a graph of maximum degree $Δ$ and a partition of its vertices into blocks of size at least $t$ . By a seminal result of Haxel…
