Abstract We attempt to present in a systematic fashion theory of critical behaviour terms simple probabilistic concepts. This approach arose out renormalization group treatments phenomena phase transitions, but it is relevant also for turbulence, certain geophysical situations, and general any statistical problem which scaling laws are expected play significant role. The presentation here reflects the recent emphasis on transitions formulation sufficiently be easily adapted different...
Following Fr\"ohlich and Spencer, we study one dimensional Ising spin systems with ferromagnetic, long range interactions which decay as $|x-y|^{-2+\alpha}$, $0\leq \alpha\leq 1/2$. We introduce a geometric description of the configurations in terms triangles play role contours for establish Peierls bounds. This particular yields direct proof well known result by Dyson about phase transitions at low temperatures.
In this paper we study the statistics of combinatorial partitions integers, which arise when studying occupation numbers loops in mean field Bose gas. We review results Lewis and collaborators get some more precise estimates on behavior at critical point (fluctuations condensate component, finite volume corrections to pressure). then prove limit shape theorems for numbers. particular that a certain range parameters, fraction total mass is, limit, supported by infinitely long loops. also show...
