Numerical analysis concerns the development of algorithms for solving all kinds of problems of continuous mathematics; it is a wide-ranging discipline having close connections with computer science, mathematics, engineering, and the sciences. Oxford's Numerical Analysis Group has long been a leader in the UK; the permanent faculty are Nick Gould, Raphael Hauser, Ian Sobey, Endre Suli, Lloyd N. (Nick) Trefethen, and Andy Wathen.
