We introduce the closed-neighborhood intersection multigraph as a useful multigraph version of the square of a graph. We characterize those multigraphs which are squares of chordal graphs and include an algorithm to go from the squared chordal graph back to its (unique!) square root. This becomes pa
## Abstract The __chordality__ of a graph __G__ = (__V, E__) is defined as the minimum __k__ such that we can write __E__ = __E__~1~ β© β¦ β© __E__~__k__~ with each (__V, E__~__i__~) a chordal graph. We present several results bounding the value of this generalization of boxicity. Our principal result
