چکیده

Abstract Uniform integer-valued Lipschitz functions on a domain of size N the triangular lattice are shown to have variations order $$\sqrt{\log N}$$ log N . The level lines such form loop O (2) model edges hexagonal with edge-weight one. An infinite-volume Gibbs measure for is constructed as thermodynamic limit and be unique. It contains only finite loops has properties indicative scale-invariance: macroscopic appearing at every scale. existence carries over height pinned origin; uniqueness does not. proof based representation via pair spin configurations that satisfy FKG inequality. We prove RSW-type estimates certain connectivity notion in aforementioned model.

On Lipschitz Ball Noncollapsing Functions and Uniform Co-lipschitz Mappings of the Plane

is called the modulus of (uniform) continuity of f . The mapping f is said to be uniformly continuous if Ω f (d) → 0 as d ↓ 0. In this case the modulus of continuity is a subadditive monotone continuous function. The definition of Ω f implies that f (Br(x)) ⊂ BΩ f (r)( f (x)). (By Bρ(y) and Bρ(y) we denote, respectively, the open and the closed ball of radius ρ, centered at y.) One important cl...

Lipschitz Functions Have Lp-Stable Persistence

We prove two stability results for Lipschitz functions on triangulable, compact metric spaces and consider applications of both to problems in systems biology. Given two functions, the first result is formulated in terms of the Wasserstein distance between their persistence diagrams and the second in terms of their total persistences.

k-Lipschitz strict triangular norms

This paper deals with Lipschitzian t-norms. A partial answer to an open problem of Alsina, Frank and Schweizer is given with regard to strict t-norms with smooth additive generators. A new notion of local Lipschitzianity for arbitrary tnorms is introduced. Some remarkable examples of non-Lipschitzian continuous triangular norms are provided.

On the Lipschitz property of strict triangular norms

This paper deals with Lipschitz triangular norms (t-norms). A partial answer to an open problem of Alsina, Frank and Schweizer is given with regard to strict t-norms with smooth additive generators. A new notion of local Lipschitz property for arbitrary t-norms is introduced. Some remarkable examples of non-Lipschitz continuous ones are provided.

Bethe ansatz solution of triangular trimers on the triangular lattice.

Recently, a model consisting of triangular trimers covering the triangular lattice was introduced and its exact free energy given. In this paper we present the complete calculation leading to this exact result. The solution involves a coordinate Bethe ansatz with two kinds of particles. It is similar to that of the square-triangle random tiling model by Widom and Kalugin. The connection of the ...
