Transversal numbers of translates of a convex body
Let F be a family of translates of a fixed convex set M in Rn. Let (F) and (F) denote the transversal number and the independence number of F, respectively. We show that (F) (F) 8 (F) − 5 for n = 2 and (F) 2n−1nn (F) for n 3. Furthermore, if M is centrally symmetric convex body in the plane, then (F) (F) 6 (F)− 3. © 2006 Elsevier B.V.

متن کاملColoring translates and homothets of a convex body
We obtain improved upper bounds and new lower bounds on the chromatic number as a linear function of the clique number, for the intersection graphs (and their complements) of finite families of translates and homothets of a convex body in R.
متن کاملTransversal of disjoint convex polygons
Given a set S of n disjoint convex polygons {Pi | 1 i n} in a plane, each with ki vertices, the transversal problem is to find, if there exists one, a straight line that goes through every polygon in S. We show that the transversal problem can be solved in O(N + n logn) time, where N = ni=1 ki is the total number of vertices of the polygons. 2002 Elsevier Science B.V. All rights reserved.
متن کاملThe Volume of the Intersection of a Convex Body with its Translates
It is proved that for a symmetric convex body K in R, if for some τ > 0, |K ∩ (x + τK)| depends on ‖x‖K only, then K is an ellipsoid. As a part of the proof, smoothness properties of convolution bodies are studied.
متن کاملTransversal numbers of uniform hypergraphs
The transversal number ~(H) of a hypergraph H is the minimum eardinality of a set of vertices that intersects all edges of H. For k ~ 1 define ck = supz(H)/(ra + n), where H ranges over all k-uniform hypergraphs with n vertices and m edges. Applying probabilistic arguments we show that ck = (1 + o ( 1 ) ) ~ , r . This settles a problem of Tuza. t ~
