Manhattan and Chebyshev flows
Lukáš Gáborik, Sascha Kurz, Giuseppe Mazzuoccolo +2
We investigate multidimensional nowhere-zero flows of bridgeless graphs. By extending the established use of the Euclidean norm, this paper considers the Manhattan and Chebyshev no…

Geometric description of -dimensional flows of a graph
Davide Mattiolo, Giuseppe Mazzuoccolo, Jozef Rajník +1
A -dimensional nowhere-zero -flow on a graph , an -NZF from now on, is a flow where the value on each edge is an element of whose (Euclidean) norm li…

Expanding vertices to triangles in cubic graphs
Giuseppe Mazzuoccolo, Vahan Mkrtchyan
Contraction of triangles is a standard operation in the study of cubic graphs, as it reduces the order of the graph while typically preserving many of its properties. In this paper…
