Gauge-Invariant Magnetic Charges in Linearised Gravity

Authors: Chris Hull, Maxwell L. Hutt, Ulf Lindström Preprint number: UUITP-11/24 Abstract: Linearised gravity has magnetic charges carried by (linearised) Kaluza-Klein monopoles. A gauge-invariant expression is found for these charges that is similar to Penrose's gauge-invariant expression for the ADM charges. A systematic search is made for other gauge-invariant charges.
