Kari Jorun Blakkisrud Hag (born April 4,1941) is a Norwegian mathematician known for her research in complex analysis on quasicircles and quasiconformal mappings,and for her efforts for gender equality in mathematics. She is a professor emerita of mathematics at the Norwegian University of Science and Technology (NTNU). [1] With Frederick Gehring she is the author of the book The Ubiquitous Quasidisk (American Mathematical Society,2012). [2]
Hag is originally from Eidsvoll. She studied at the Norwegian School of Education in Trondheim ,completing a cand.mag. in 1963,and then at the University of Oslo,completing a cand.real. in 1967. [3] [4] Following this,she earned her doctorate in 1972 from the University of Michigan. Her dissertation,Quasiconformal Boundary Correspondences and Extremal Mappings,was supervised by Gehring. [5]
After completing her doctorate,she joined the Norwegian Institute of Technology (NTH),which later became part of NTNU. [4] She became a full professor at NTNU in 2001,and retired as a professor emerita in 2011. [3]
NTNU gave Hag their gender equality award in 2000,for her efforts to increase the interest of girls in science and mathematics. [6] In 2018 she was elected as a knight in the Order of St. Olav. [3]
