Nicholas Stephen Manton is a mathematician at the University of Cambridge whose work has mostly concerned solitons in particle physics. He is perhaps best known for his paper on sphalerons and for his work on the interaction of BPS monopoles. He has also worked on skyrmions and, with Michael Atiyah, proposed a new class of approximate solutions derived from instantons. He was elected a Fellow of the Royal Society in 1996 (Royal Society 2008).
