John Rainwater is the pseudonym of a fictitious mathematician, in whose name mathematicians publish papers. Rainwater has worked mainly in functional analysis
Functional analysis
Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure and the linear operators acting upon these spaces and respecting these structures in a suitable sense...

Convex function
In mathematics, a real-valued function f defined on an interval is called convex if the graph of the function lies below the line segment joining any two points of the graph. Equivalently, a function is convex if its epigraph is a convex set...

Creation

Rainwater was invented by graduate students at the University of Washington in 1952, when students used an extra registration-form to enroll Rainwater in a course on real functions. Students submitted homework for Rainwater throughout the semester, until the Professor picked up a fountain pen with Rainwater's name, which exploded!

Mathematicians publishing as Rainwater

Many internationally renowned mathematicians have published under the name of John Rainwater. John Isbell wrote Rainwater's first, second, and tenth papers; by 2002, Isbell had also written or coauthored six other pseudonymous papers under two other names. Functional analyst Robert R. Phelps wrote the third, ninth, eleventh (an unpublished note for the Rainwater seminar), twelfth, and thirteenth (with Peter D. Morris), fifteenth (with Isaac Namioka), and sixteenth (with David Preiss
