Sheldon Jay Axler (born 6 November 1949, Philadelphia) is an American mathematician, professor of mathematics and the Dean of the College of Science and Engineering at San Francisco State University. He has made contributions to mathematics education, publishing several mathematics textbooks.
He went to Palmetto High School at Miami, Florida (1967). He obtained his AB in mathematics with highest honors at Princeton University (1971) and his PhD in mathematics, under professor Donald Sarason, from the University of California, Berkeley (1975, Dissertation: "Subalgebras of "). As a postdoc he was a C. L. E. Moore instructor at the Massachusetts Institute of Technology.
He taught for many years and became a Full Professor at Michigan State University. In 1997 Axler moved to San Francisco State University where he became the Chair of the Mathematics Department.
Axler received the Lester R. Ford Award for expository writing in 1996 from the Mathematical Association of America. In the awarded paper, "Down With Determinants!", Axler shows "how linear algebra can be done better without determinants". In 2012 he became a fellow of the American Mathematical Society.
He was an Associate Editor of the American Mathematical Monthly and the Editor-in-Chief of the Mathematical Intelligencer.
Axler's book Linear Algebra Done Right eschews the use of determinants, in favor of other methods.
