چکیده

In this paper, we study the number of compact sets needed in an infinite family of convex sets with a local intersection structure to imply a bound on its piercing number, answering a conjecture of Erdős and Grünbaum. Namely, if in an infinite family of convex sets in Rd we know that out of every p there are q which are intersecting, we determine if having some compact sets implies a bound on the number of points needed to intersect the whole family. We also study variations of this problem.

Happy Endings of noncrossing convex bodies . joint work with :

We introduce a combinatorial invariant of arrangements of compact convex sets in the plane, generalizing the notion of the order type of planar point sets. This allows us to define and study realization spaces, extending previous work on representability and isotopy by Levi, Ringel, Folkman and Lawrence, Goodman and Pollack, and Mnëv. With these tools at hand we attack the generalized Erdős-Sze...

Functionally closed sets and functionally convex sets in real Banach spaces

‎Let $X$ be a real normed  space, then  $C(subseteq X)$  is  functionally  convex  (briefly, $F$-convex), if  $T(C)subseteq Bbb R $ is  convex for all bounded linear transformations $Tin B(X,R)$; and $K(subseteq X)$  is  functionally   closed (briefly, $F$-closed), if  $T(K)subseteq Bbb R $ is  closed  for all bounded linear transformations $Tin B(X,R)$. We improve the    Krein-Milman theorem  ...

Geometric Intersection Patterns and the Theory of Topological Graphs

The intersection graph of a set system S is a graph on the vertex set S, in which two vertices are connected by an edge if and only if the corresponding sets have nonempty intersection. It was shown by Tietze (1905) that every finite graph is the intersection graph of 3-dimensional convex polytopes. The analogous statement is false in any fixed dimension if the polytopes are allowed to have onl...

Helly-type problems for convex quadrilaterals in the plane

A family of sets in the plane is said to have a 3-transversal if there exists a set of 3 points such that each member of the family contains at least one of them. A conjecture of Grünbaum’s says that a planar family of translates of a convex compact set has a 3-transversal provided that any two of its members intersect. Recently the conjecture has been proved affirmatively (see [1]). We provide...

An inequality concerning edges of minor weight in convex 3-polytopes

Let eij be the number of edges in a convex 3–polytope joining the vertices of degree i with the vertices of degree j. We prove that for every convex 3-polytope there is 20e3,3 +25e3,4 +16e3,5 +10e3,6 + 6 2 3 e3,7+5e3,8+2 1 2 e3,9+2e3,10+16 2 3 e4,4+11e4,5+5e4,6+1 2 3 e4,7+5 1 3 e5,5+ 2e5,6 ≥ 120; moreover, each coefficient is the best possible. This result brings a final answer to the conjectur...
