WebSo the more a point on the critical surface is close to the fixed point, the shorter correlation length it has, so for points arbitrary close to the critical point the correlation length goes to zero and then suddenly it jumps to infinite exactly at the fixed point. It seems really strange. – Hossein Aug 3, 2016 at 20:58 flocked resin
