Gerd Grubb (born 1939)[1][2] is a Danish mathematician known for her research on pseudo-differential operators. She is a professor emerita in the Department of Mathematical Sciences at the University of Copenhagen,[3] where she was the first female professor of mathematics.[4]
Grubb was born on 12 February 1939 in Copenhagen, the daughter of two chemical engineers. She was a student at the Øregård Gymnasium,[1] and then studied various sciences at the University of Copenhagen from 1956 until 1959. After earning a master's degree in mathematics at Aarhus University in 1963, she went to Stanford University for doctoral study in mathematics, completing a Ph.D. in 1966.[5] Her dissertation, A Characterization of the Non-Local Boundary Value Problems Associated With an Elliptic Operator, was supervised by Ralph S. Phillips.[6] She completed a habilitation (Dr. Phil.) in 1975 at the University of Copenhagen, with the habilitation thesis Semiboundedness and other properties of normal boundary problems for elliptic partial differential operators.[5]
She returned to the University of Copenhagen as an assistant professor in 1966, eventually becoming a full professor there in 1994.[1]
Grubb is the author of the books Functional calculus of pseudodifferential boundary problems (Progress in Mathematics 65, Birkhäuser, 1986; 2nd ed., 1996)[7] and Distributions and operators (Graduate Texts in Mathematics 252, Springer, 2009).[8]
Grubb is a member of the Danish Academy of Natural Sciences[1][9] The University of Reims Champagne-Ardenne gave her an honorary doctorate in 1988.[1][2][5] She was promoted to hedersdoktor (an honorary doctorate) at the University of Lund (Sweden) in 2016.[10] In 2020, she received the Gold Medal of the Royal Danish Academy of Sciences and Letters.[4]
