Counting edge-colorings of a complete graph avoiding a rainbow

Fabricio S. Benevides, Josefran de O. Bastos

For natural numbers let be the number of -edge-colorings of that do not contain a rainbow copy of a , that is, a copy of in which all e…

Gallai 3-colourings of random graphs

Fabrício S. Benevides, Rubens C. S. Monteiro, Guilherme O. Mota

A Gallai -colouring of a graph is a colouring of with colours that induces no rainbow triangles, that is, a triangle with edges of 3 different colours. We give a…

Partitioning 2-edge-coloured bipartite graphs into monochromatic cycles

Fabrício Siqueira Benevides, Arthur Lima Quintino, Alexandre Talon

Given an -edge-colouring of the edges of a graph , we say that it can be partitioned into monochromatic cycles when there exists a set of vertex-disjoint monochromati…

Maximizing the expected number of components in an online search of a graph

Fabrício Siqueira Benevides, Małgorzata Sulkowska

The following optimal stopping problem is considered. The vertices of a graph are revealed one by one, in a random order, to a selector. He aims to stop this process at a time…

The number of Gallai k-colorings of complete graphs

Josefran de Oliveira Bastos, Fabricio S. Benevides, Jie Han

An edge coloring of the -vertex complete graph, , is a Gallai coloring if it does not contain any rainbow triangle, that is, a triangle whose edges are colored with three d…

Counting Gallai 3-colorings of complete graphs

Josefran de Oliveira Bastos, Fabricio Siqueira Benevides, Guilherme Oliveira Mota +1

An edge coloring of the n-vertex complete graph K_n is a Gallai coloring if it does not contain any rainbow triangle, that is, a triangle whose edges are colored with three distinc…

Edge-colorings of graphs avoiding complete graphs with a prescribed coloring

Fabricio S. Benevides, Carlos Hoppen, Rudini Menezes Sampaio

Given a graph and an integer , a partition of the edge set of into at most classes, and a graph , define as the number…

Circular Backbone Colorings: on matching and tree backbones of planar graphs

Julio Araujo, Fabricio Benevides, Alexandre Cezar +1

Given a graph , and a spanning subgraph of , a circular -backbone -coloring of is a proper -coloring of such that $q\le \lvert c(u)-c(v)\rvert \l…

Generalising separating families of fixed size

Fabrício S. Benevides, Dániel Gerbner, Cory T. Palmer +1

We examine the following version of a classic combinatorial search problem introduced by Rényi: Given a finite set of elements we want to identify an unknown subset $Y \sub…

Maximum percolation time in two-dimensional bootstrap percolation

Fabricio Benevides, Michał Przykucki

We consider a classic model known as bootstrap percolation on the square grid. To each vertex of the grid we assign an initial state, infected or healthy, and then in…
