Absolute continuity of near-critical 3-Potts and 4-Potts FK scaling limits
Consider FK percolation for the 3-state and 4-state Potts models, with inverse temperatures and satisfying
These shifts correspond to the expected correlation exponents for and for . Potts absolute-continuity conjecture. FK percolation for 3-Potts and 4-Potts has near-critical scaling limits under these temperature shifts, and, under for example the quad topology , these near-critical scaling limits are absolutely continuous with respect to the critical scaling limits. The critical scaling limits are not known to be unique, so the conjecture includes a statement about absolute continuity relative to whichever critical limits exist.
