Eivind Eriksen

Professor in Mathematics at BI Norwegian Business School. Author of several textbooks in mathematics, and coauthor of the research monograph Noncommutative Deformation Theory. Investor in common stocks, mostly on Oslo Børs and NYSE/Nasdaq.


My main research interests are noncommutative deformation theory and noncommutative algebraic geometry, differential structures in algebraic geometry (rings of differential operators, connection on modules, D-modules), and representation theory. For details on my research, see research and publications.
