Suppose that instead of ^↑√u clusters, each with universe size ^↓√u, we constructed vEB trees to have u^1/k clusters, each with universe size u^1-1/k, where k > 1 is a constant. If we were to modify the operations appropriately, what would be their running times? For the purpose of analysis, assume that u^1/k and u^1-1/k are always integers.
