Lawrence Clinton Washington (born 1951, in Vermont) is an American mathematician at the University of Maryland who specializes in number theory.
[citation needed] He was named to the 2023 class of Fellows of the American Mathematical Society, "for contributions to number theory, especially cyclotomic fields, and for mentoring at all levels".
He wrote a treatise with Allan Adler on their discovery of a connection between higher-dimensional analogues of magic squares and p-adic L-functions.
[3] Washington has done important work on Iwasawa theory, Cohen-Lenstra heuristics, and elliptic curves and their applications to cryptography.
[4] More recently, Washington has published on arithmetic dynamics, sums of powers of primes, and Iwasawa invariants of non-cyclotomic Zp extensions
