List strong and list normal edge-coloring of (sub)cubic graphs

Borut Lužar, Edita Máčajová, Roman Soták +1

A strong edge-coloring of a graph is a proper edge-coloring, in which the edges of every path of length 3 receive distinct colors; in other words, every pair of edges at distance a…

Degree-balanced decompositions of cubic graphs

Borut Lužar, Jakub Przybyło, Roman Soták

We show that every cubic graph on vertices contains a spanning subgraph in which the number of vertices of each degree deviates from by at most , up…

Packing coloring of hypercubes with extended Hamming codes

Petr Gregor, Jaka Kranjc, Borut Lužar +1

A {\em packing coloring} of a graph is a mapping assigning a positive integer (a color) to every vertex of such that every two vertices of color are at distance at leas…

Normal 5-edge-coloring of some snarks superpositioned by Flower snarks

Jelena Sedlar, Riste Škrekovski

An edge e is normal in a proper edge-coloring of a cubic graph G if the number of distinct colors on four edges incident to e is 2 or 4: A normal edge-coloring of G is a proper edg…

Revisiting Semistrong Edge-Coloring of Graphs

Borut Lužar, Martina Mockovčiaková, Roman Soták

A matching in a graph is {\em semistrong} if every edge of has an endvertex of degree one in the subgraph induced by the vertices of . A {\em semistrong edge-colorin…

3-facial edge-coloring of plane graphs

Mirko Horňák, Borut Lužar, Kenny Štorgel

An -facial edge-coloring of a plane graph is a coloring of its edges such that any two edges at distance at most on a boundary walk of any face receive distinct colors…

Strong edge colorings of graphs and the covers of Kneser graphs

Borut Lužar, Edita Mačajová, Martin Škoviera +1

A proper edge coloring of a graph is strong if it creates no bichromatic path of length three. It is well known that for a strong edge coloring of a -regular graph at least $2k-…

Strong edge coloring of subcubic bipartite graphs

Borut Lužar, Martina Mockovčiaková, Roman Soták +1

A strong edge coloring of a graph is a proper edge coloring in which each color class is an induced matching of . In 1993, Brualdi and Quinn Massey proposed a conjecture tha…
