Recurrence conjecture for IID -rotor walks
Recurrence conjecture for IID -rotor walks
Let . On , a -rotor walk is the walk in which, at each step, the rotor at the walker's current location is rotated degrees counterclockwise with probability and degrees clockwise with probability . Let be sampled from the IID uniform measure on .
-rotor recurrence conjecture. For almost every such , the corresponding -rotor walk on visits every vertex infinitely many times almost surely.
The claim extends the recurrence question across the full parameter range , including the horizontal-vertical walk at . The supplied text gives no resolution and explains that the methods in the paper are sensitive to changes in the model.
