Hirsch, M. W. (ed.) et al., From topology to computation: Proceedings of the Smalefest. Papers presented at the conference “From topology to computation: Unity and diversity in the mathematical sciences” held at the University of California at Berkeley, USA, August 5-9, 1990 in honor of Stephen Smale’s 60th birthday. New York: Springer-Verlag. 83-106 (1993).
This paper is a very detailed description of Stephen Smale’s work in differential topology. The topics discussed are immersions, diffeomorphisms of spheres, the Poincaré conjecture, handlebodies, and the $$h$$-cobordism theorem.
