We find that the BPS equations are unchanged outside a quantum core where higher dimension contributions are expected to be important. We find two quantum generalizations of the BPS soliton. The leading higher-derivative correction to the effective action is shown not to contribute to the BPS mass formula.31 pages, Latex, 10 figures (eps), minor statement correctedHigh Energy Physics - Theorytext
