We discuss the relation between the Ramond-Ramond charges of D-branes and the topology of Chan-Paton vector bundles. We show that a topologically nontrivial normal bundle induces RR charge and that the result fits in perfectly with the proposal that D-brane charge is the topology of the Chan-Paton bundle, regarded as an element of K

Bill Paton's principal career was in experimental pharmacology, and from his student days he was marked for distinction. He took first class honours at Oxford University and won gold medals during his clinical training at University College Hospital. He was a Reader at the age of 35, a Professor two years later, and a Fellow of the Royal Society before he was 40. He returned to Oxford as Profes...
