Nash returned to his academic research once the disease was in remission, and for his landmark work on the mathematics of game theory he shared the 1994 Nobel memorial economics prize with Hungarian-American economist John Harsanyi and German mathematician and economist Reinhard Selten. In 2015 he shared the Abel Prize (in mathematics) with Louis Nirenberg for their work on nonlinear partial differential equations. Nash wrote Essays on Game Theory (1997).
