In 2023, we published an updated English edition of the László Fejes Tóth's 'Lagerungen', a landmark monograph in discrete geometry. The original German book was published 70 years earlier. The new book ("very appealing" according to MathSciNet) covers the state of the art. [1/2]

Spanning Trees with Few Branch Vertices in a Chair-Free Graph

Graphs and Combinatorics - If one edge of a claw is subdivided, the resulting graph is called a chair. Spanning trees in claw-free graphs have been widely studied, but we are unable to find prior...

On r-wise t-intersecting Uniform Families

Combinatorica - We consider families, $$\mathcal {F}$$ of k-subsets of an n-set. For integers $$r\ge 2$$ , $$t\ge 1$$ , $$\mathcal {F}$$ is called r-wise t-intersecting if any r of its members have...
