P adic Numbers p adic analysis and zeta functions Neal Koblitz was a student of Nicholas M. Katz under whom he received his Ph.D. in mathematics at Princeton in 1974. He spent the year 1974 75 and the spring semester 1978 in Moscow where he did research in p adic analysis and also translated Yu. I. Manins Course in Mathematical Logic (GTM 53). He taught at Harvard from 1975 to 1979 and since 1979 has been at the University of Washington in Seattle. He has published papers in number theory algebraic geometry and p adic analysis and he is the author of p adic Analysis: A Short Course on Recent Work (Cambridge University Press and GTM 97: Introduction to Elliptic Curves and Modular Forms (Springer Verlag)
