Bounds on the game isolation number and exact values for paths and cycles

Csilla Bujtás, Tanja Dravec, Michael A. Henning +1

The isolation game is played on a graph by two players who take turns playing a vertex such that if is the set of already played vertices, then a vertex can be selected onl…

A proof of the -conjecture for independent domination in cubic graphs

Boštjan Brešar, Tanja Dravec, Michael A. Henning

A set of vertices in a graph is a dominating set of if every vertex not in is adjacent to a vertex in~. An independent dominating set in is a dominating set…

Identifying codes in graphs of given maximum degree: Characterizing trees

Dipayan Chakraborty, Florent Foucaud, Michael A. Henning +1

An identifying code of a closed-twin-free graph is a dominating set of vertices of such that any two vertices in have a distinct intersection between their closed n…

On the isolation number of graphs with minimum degree four

Wayne Goddard, Michael A. Henning

An isolating set in a graph is a set of vertices such that removing and its neighborhood leaves no edge. The isolation number of (also known as the vertex-e…
