About
Trygve Johnsen is a Professor of Pure Mathematics at the Department of Mathematics and Statistics, UiT The Arctic University of Norway. His research bridges algebraic geometry with error-correcting codes, focusing on matroid theory, coding theory, and combinatorial structures. He is affiliated with the research group Applied and Computational Algebra and the Albatros project on mathematical aspects of information transmission.
- Education: PhD in Mathematics (University of Oslo, 1984)
- Research Interests: Algebraic Geometry, Coding Theory, Matroid Theory, Combinatorics, Algebraic Methods in Coding
His recent work explores symmetric determinantal varieties, q-matroid analogues, and generalized weight spectra of codes. Scientific contributions include foundational studies on Grassmannians, Stanley-Reisner rings, and Betti numbers in coding theory.
Doctoral Students: Supervised 5 PhD candidates including Andreas L. Knutsen and Jan Roksvold.
