Strongly equitable Ore-degree list-coloring conjecture

For a graph GG, define its Ore-degree by

Θ(G):=max{d(x)+d(y):xyE(G)}.\Theta(G):=\max\{d(x)+d(y):xy\in E(G)\}.

A graph is SE kk-choosable if every kk-list assignment admits a strongly equitable list coloring. Strongly equitable Ore-degree conjecture. If

2k>Θ(G),2k>\Theta(G),

then GG is SE kk-choosable. This is proposed as the strongly equitable analogue of the Ore-degree list-coloring conjecture.
