![]() ![]() His latest publication appeared in the March 2010 issue of the American Mathematical Monthly, entitled "Old and New Results in the Foundations of Elementary Euclidean and Non-Euclidean Geometries" a copy of that paper is sent along with the Instructors' Manual to any instructor who requests it. In later years, he published some articles on the foundations of geometry, most of whose results are included in his Freeman text. He is also the translator of Serre’s Corps Locaux. Serre named after him and an approximation theorem J. His early journal publications are in the subject of algebraic geometry, where he discovered a functor J.-P. ![]() His Freeman text Euclidean and Non-Euclidean Geometries: Development and History had its first edition appear in 1974, and is now in its vastly expanded fourth edition. His second book Lectures on Forms in Many Variables (Benjamin, 1969) was about the subject started by Serge Lang in his thesis and subsequently developed by himself and others, culminating in the great theorem of Ax and Kochen showing that the conjecture of Emil Artin that p-adic fields are C2 is "almost true" (Terjanian found the first counter-example to the full conjecture). His first published book was Lectures on Algebraic Topology (Benjamin, 1967), which was later expanded into a joint work with John Harper, Algebraic Topology: A First Course (Westview, 1981). He took early retirement from that campus at age 57. in Paris), an Associate Professor at Northeastern University for two years, and Full Professor at U.C. Berkeley for five years (two years of which he spent on NSF Postdoctoral Fellowships at Harvard and at the I.H.E.S. He was subsequently an Assistant Professor at U.C. His PhD is from Princeton University, his thesis adviser having been the brilliant and fiery Serge Lang. He received his undergraduate degree from Columbia University, where he was a Ford Scholar.
