An asymptotic lower bound on the number of polyominoes

Vuong Bui

Let $P (n)$ be the number of polyominoes of $n$ cells and $λ$ be Klarner's constant, that is, $λ = lim_{n \to \infty} n P (n)$ . We show that there exist some positive numbers $A…

Every generating polytope is strongly monotypic

Vuong Bui

We prove an old conjecture of McMullen, Schneider and Shephard that every polytope with the generating property is strongly monotypic. The other direction is already known, which i…

The square of a Hamilton cycle in randomly perturbed graphs

Julia Böttcher, Olaf Parczyk, Amedeo Sgueglia +1

We investigate the appearance of the square of a Hamilton cycle in the model of randomly perturbed graphs, which is, for a given $α \in (0, 1)$ , the union of any $n$ -vertex graph wit…
