Disconnected graphs and extremal bounds for realizable distance orders
Gerardo L. Maldonado, Leonardo Martínez-Sandoval, Miguel Raggi +1
Let be a graph together with a total order on its edges. We say that is realizable in if there is a placement of the vertices of in $\mathbb{…
Total orders realizable as the distances between two sets of points
Gerardo L. Maldonado, Miguel Raggi Pérez, Edgardo Roldán-Pensado
In this note we give a negative answer to a question proposed by Almendra-Hernández and Martínez-Sandoval. Let be positive integers and let and be sets of sizes $n…
A note on the tolerated Tverberg theorem
Natalia García-Colín, Miguel Raggi, Edgardo Roldán-Pensado
In this paper we give an asymptotically tight bound for the tolerated Tverberg Theorem when the dimension and the size of the partition are fixed. To achieve this we study certain…
A sunflower anti-Ramsey theorem and its applications
Leonardo Martínez-Sandoval, Miguel Raggi, Edgardo Roldán-Pensado
A -sunflower in a hypergraph is a family of edges with vertices in common. We show that if we colour the edges of a complete hypergraph in such a way that any monochromatic…
Flag Bicolorings, Pseudo-Orientations, and Double Covers of Maps
Hiroki Koike, Daniel Pellicer, Miguel Raggi +1
This paper discusses consistent flag bicolorings of maps and maniplexes, in their own right and as generalizations of orientations and pseudo-orientations. Furthermore, a related d…
