William B. Johnson (mathematician)

William Buhmann Johnson (born December 5, 1944 in Palo Alto , California ) is an American mathematician .

William B. Johnson graduated from Southern Methodist University in 1966 with a degree in mathematics, and received his doctorate in 1969 with the dissertation Operator and Dual Operator Bases in Linear Topological Spaces under James Dyer . From 1969 to 1971 he was an assistant professor and then until 1973 a lecturer at the University of Houston . He then taught as a professor at Ohio State University until 1986, interrupted by stays at the University of Texas at Austin (1975), at the Hebrew University of Jerusalem (1976-1977), at the École polytechnique (March and April 1980) and finally at Texas A&M University (Fall 1981). At this last station he accepted a professorship in 1984, which he still holds today. Further stays were the California Institute of Technology (May and June 1989), Weizmann Institute of Science (January to March 1994), Mathematical Sciences Research Institute (spring 1996) and again at the Weizmann Institute of Science (January to June 2002).

His main research area is the Banach space theory , but he also works in non-linear functional analysis , probability theory and operator theory .

Johnson is a Fellow of the American Mathematical Society and the Mathematical Association of America , as well as an intermittent co-editor of several prestigious mathematical journals, including Transactions and Memoirs of the American Mathematical Society , Geometric and Functional Analysis , Mathematische Annalen , and others. The Polish Academy of Sciences awarded him the Stefan Banach Medal in 2007 .
