چکیده

It is shown that there exists a number d 0 < 8(2 p 3?3)=3 = 1:237604::, such that every compact convex set K with an interior point admits a covering of the plane with density smaller than or equal to d 0. This improves on the previous result 9], which showed that a density of 8(2 p 3 ? 3)=3 can always be obtained. Since the thinnest covering of the plane with congruent circles is of density 2= p 27 = 1:20919. . ., we strengthen the case for the conjecture that the smallest such number d 0 is 2= p 27.

Covering the Plane with Congruent Copies of a Convex Body

It is shown that every plane compact convex set /f with an interior point admits a covering of the plane with density smaller than or equal to 8(2\/3 — 3)/3 = 1.2376043 For comparison, the thinnest covering of the plane with congruent circles is of density 2n/\Z21 = 1.209199576... (see R. Kershner [3]), which shows that the covering density bound obtained here is close to the best possible. It ...

Convexity and Combinatorics

Geir Agnarsson. George Mason University, Fairfax, VA. On Minkowski sum of simplices and their flags. We consider a Minkowski sum of k standard simplices in Rr and its chains of faces, for given k, r ∈ N. We define its flag polynomial in a direct and canonical way in terms of the k-th master polytope P (k). This polynomial is related to the well-known flag vector, and it has some nice algebraic ...

Covering a Disk by Disks

For a convex body C in R, what is the smallest number f = fd(C) such that any sequence of smaller homothetic copies of C whose total volume is at least f times the volume of C permits a translative covering of C? László Fejes Tóth conjectured in 1984 that f2(C) ≤ 3 for any convex body C in the plane. This conjecture has been only confirmed for parallelograms and triangles: Moon and Moser had sh...

Covering and Piercing Disks with Two Centers

We give exact and approximation algorithms for two-center problems when the input is a set D of disks in the plane. We first study the problem of finding two smallest congruent disks such that each disk in D intersects one of these two disks. Then we study the problem of covering the set D by two smallest congruent disks.

Clouds of Planar Convex Bodies

Let fK; K 1 ; : : : ; K n g be a family of convex bodies in the plane. We say that the bodies K 1 ; : : : ; K n form a deep cloud around K if the bodies K; K 1 ; : : : ; K n are mutually non-overlapping and every ray emanating from K intersects the interior of at least one of K 1 ; : : : ; K n. In this paper we are concerned with the following question: What is the minimum number of congruent c...
