Frank Grosshans

Frank Grosshans is an American mathematician who works in invariant theory, where he is known for the discovery of Grosshans subgroups and Grosshans graded coefficients. He is a professor of mathematics at West Chester University, Pennsylvania. Grosshans has been an invited speaker at meetings of the Mathematical Association of America.
He received his B.S. from the University of Illinois and his Ph.D. in mathematics from the University of Chicago. He taught at University of Pennsylvania and Johns Hopkins University before joining the West Chester University.
