The Edge Spectrum of Maximal k-Colorable Graphs
Ryan Brij-Raj · New York University
Abstract A graph G on n vertices is maximal k-colorable if χ(G) = k and adding any edge raises the chromatic number — equivalently, G is a complete k-partite graph. This paper studies the edge spectrum Σχ(n, k): the set of all edge counts realized by such graphs. We prove the saturation number satχ(n, k) = (k−1)(2n−k)/2 and the abundance abχ(n, k) = ex(n, Kk+1). We show Σχ(n, k) is a complete integer interval if and only if n ≤ k + 2, determine Σχ(n, 2) exactly with explicit gap formulas, and give a parametric description for k = 3 including identification of the first partition collision at n = 9. We also establish the strict containment Σχ(n, k) ⊊ ES(n, Kk+1) for n ≥ k + 3.
