Large Deviations in the Geometry of Convex Lattice Polygons
نویسنده
چکیده
We provide a full large deviation principle (LDP) for the uniform measure on certain ensembles of convex lattice polygons. This LDP provides for the analysis of concentration of the measure on convex closed curves. In particular, convergence to a limiting shape results in some particular cases, including convergence to a circle when the ensemble is deened as those centered convex polygons, with vertices on a scaled two dimensional lattice, and with length bounded by a constant. The Gauss-Minkowskii transform of convex curves plays a crucial role in our approach.

A convex combinatorial property of compact sets in the plane and its roots in lattice theory
K. Adaricheva and M. Bolat have recently proved that if $,mathcal U_0$ and $,mathcal U_1$ are circles in a triangle with vertices $A_0,A_1,A_2$, then there exist $jin {0,1,2}$ and $kin{0,1}$ such that $,mathcal U_{1-k}$ is included in the convex hull of $,mathcal U_kcup({A_0,A_1, A_2}setminus{A_j})$. One could say disks instead of circles.Here we prove the existence of such a $j$ and $k$ ...
متن کاملLimit shape of optimal convex lattice polygons in the sense of different metrics
Classes of convex lattice polygons which have minimal lp–perimeter with respect to the number of their vertices are said to be optimal in the sense of lp metric. The purpose of this paper is to prove the existence and explicitly find the limit shape of the sequence of these optimal convex lattice polygons as the number of their vertices tends to infinity. It is proved that if p is arbitrary int...
متن کاملConvex $L$-lattice subgroups in $L$-ordered groups
In this paper, we have focused to study convex $L$-subgroups of an $L$-ordered group. First, we introduce the concept of a convex $L$-subgroup and a convex $L$-lattice subgroup of an $L$-ordered group and give some examples. Then we find some properties and use them to construct convex $L$-subgroup generated by a subset $S$ of an $L$-ordered group $G$ . Also, we generalize a well known result a...
متن کاملAn Inequality for Adjoint Rational Surfaces
We generalize an inequality for convex lattice polygons – aka toric surfaces – to general rational surfaces. Our collaboration started when the second author proved an inequality for algebraic surfaces which, when translated via the toric dictionary into discrete geometry, yields an old inequality by Scott [5] for lattice polygons. In a previous article [2], we were then able to refine this est...
متن کاملOn fuzzy convex lattice-ordered subgroups
In this paper, the concept of fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) of an ordered group (resp. lattice-ordered group) is introduced and some properties, characterizations and related results are given. Also, the fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) generated by a fuzzy subgroup (resp. fuzzy subsemigroup) is characterized. Furthermore,...
