Today we received our first citation. It's taken about 18 months, which is longer than expected, however we're extremely pleased and are hoping for another two citations by end of July. The paper was co-written by Dr Olivier and Dr Molchan of UCT's Applied Mathematics department and Prof Herbst of Stellenbosch's Applied Mathematics department. The paper has been published in IOP's Journal of Physics and can be viewed here. (IOP account required if not opened from inside UCT's firewall).
