The critical group of the Kneser graph on $2$ -subsets of an $n$ -element set

Joshua E. Ducey, Ian Hill, Peter Sin

In this paper we compute the critical group of the Kneser graph $K G (n, 2)$ . This is equivalent to computing the Smith normal form of a Laplacian matrix of this graph.

Kirigami Actuators

Marcelo A. Dias, Michael P. McCarron, Daniel Rayneau-Kirkhope +4

Thin elastic sheets bend easily and, if they are patterned with cuts, can deform in sophisticated ways. Here we show that carefully tuning the location and arrangement of cuts with…

SONS: The JCMT legacy survey of debris discs in the submillimetre

Wayne S. Holland, Brenda C. Matthews, Grant M. Kennedy +32

Debris discs are evidence of the ongoing destructive collisions between planetesimals, and their presence around stars also suggests that planets exist in these systems. In this pa…
