Luiz Emilio Allem, Carlos Hoppen, Matheus Micadei Marzo +1
The aim of this paper is to analyse the evolution of the COVID-19 pandemic in Rio Grande do Sul by applying graph-theoretical tools, particularly spectral clustering techniques, on…
The rainbow Erdős-Rothschild problem for the Fano plane
Lucas de Oliveira Contiero, Carlos Hoppen, Hanno Lefmann +1
The Fano plane is the unique linear 3-uniform hypergraph on seven vertices and seven hyperedges. It was recently proved that, for all , the balanced complete bipartite 3-…
A note on a stability result for the Fano plane
Carlos Hoppen, Hanno Lefmann, Knut Odermann
In this note, we adapt the Keevash-Sudakov proof of the (Turán) Stability Theorem for the Fano plane to find an explicit dependency between the parameters and . Th…
