Generalized Nordhaus--Gaddum Inequalities for Eigenvalues

Sahil Agarwal, Carter Antley, Joseph Aulenbacher +6

For a graph $G$ , let $I^»_{1} (G) \geq I^»_{2} (G) \geq \dots \geq I^»_{n} (G)$ denote the adjacency eigenvalues of $G$ . We investigate the asymptotic maximum of \[ Î»_i(G)+Î»_j(\overline G) \] f…

Covering complete $r$ -partite hypergraphs with few monochromatic components

Luke Hawranick, Ruth Luo

An edge-coloring of a hypergraph is {\em spanning} if every vertex sees every color used in the coloring. In this paper, we prove that for $k \geq 2 r \geq 6$ , in any spanning $k$ -c…
