Kari Jorun Blakkisrud Hag (1941–2026) was 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 was a professor 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]

Education and career

Hag was 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]

Awards and honors

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]
