In 1911, Toeplitz made a conjecture asserting that every Jordan curve in \(\mathbb{R}^{2}\) contains four points forming the corners of a square. Here Conjecture C is presented, which states that the side length of the largest square on a closed curv

In 1962, S. L. Hakimi proved necessary and sufficient conditions for a given sequence of positive integers d"1,d"2,...,d"n to be the degree sequence of a non-separable graph or that of a connected graph. Our goal in this note is to utilize these resu

In the paper, I first try to give some impression of Norwegian contributions to combinatorics in the 20th century. This is followed by some remarks on my own combinatorial experiences.

We raise a conjecture which would generalize Radon's theorem and would provide combinatorial proof for the result from [7], which generalizes Rado's theorem on general measure and the Ham sandwich theorem.We proved that the conjecture holds in severa

Let F be a finite family of disjoint translates of a compact convex set K in R 2, and let l be an ordered line meeting each of the sets. Then l induces in the obvious way a total order on F. It is known that, up to reversals, at most three different
