Resumen de Classification of half-planar maps

Omer Angel, Gourab Ray

• We characterize all translation invariant half-planar maps satisfying a certain natural domain Markov property. For p-angulations with p≥3 where all faces are simple, we show that these form a one-parameter family of measures H(p)α. For triangulations, we also establish existence of a phase transition which affects many properties of these maps. The critical maps are the well-known half-plane uniform infinite planar maps. The subcritical maps are identified as all possible limits of uniform measures on finite maps with given boundary and area.
