Influence Sectors: At the end of the Combat Phase, if you have at least one Ship in a Sector (including Sectors where no battle took place) that has no Population Cubes (including Orbitals), remove the Controlling player's Influence Disc and place it on their Influence Track. Next, you may move Influence Discs from your Influence Track to any Sector where you have a Ship and no Influence Disc is present (including Sectors where other players' Influence Discs were just removed).
