The maximum diameter of -dimensional simplicial complexes

Stefan Glock, Olaf Parczyk, Silas Rathke +1

For every fixed dimension and sufficiently large , we determine the maximum possible diameter of a strongly connected -dimensional simplicial complex on vertices. Thi…

The maximum diameter of 2-dimensional simplicial complexes

Olaf Parczyk, Silas Rathke, Tibor Szabó

We study a problem of Santos about the largest possible diameter of a -dimensional (abstract) simplicial complex on vertices. For dimension 2, we determine the exact value o…

Adjunctions, Box Products, and Forcing Families

Aldo Kiem, Olaf Parczyk, Christoph Spiegel

Sidorenko's conjecture states that the number of copies of any given bipartite graph in another graph of given density is asymptotically minimized by a random graph. For bipartite…

An Unsure Note on an Un-Schur Problem

Olaf Parczyk, Christoph Spiegel

Graham, Rödl, and Ruciński originally posed the problem of determining the minimum number of monochromatic Schur triples that must appear in any 2-coloring of the first integer…

Dirac's theorem for graphs of bounded bandwidth

Alberto Espuny Díaz, Pranshu Gupta, Domenico Mergoni Cecchelli +2

We provide an optimal sufficient condition, relating minimum degree and bandwidth, for a graph to contain a spanning subdivision of the complete bipartite graph . This…

Spanning spheres in Dirac hypergraphs

Freddie Illingworth, Richard Lang, Alp Müyesser +2

We show that a -uniform hypergraph on vertices has a spanning subgraph homeomorphic to the -dimensional sphere provided that has no isolated vertices and each s…

On product Schur triples in the integers

Letícia Mattos, Domenico Mergoni Cecchelli, Olaf Parczyk

Schur's theorem states that in any -colouring of the set of integers there is a monochromatic solution to , provided is sufficiently large. Abbott and Wang stud…
