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. I am @eivinderiksen on Twitter, and Eivind Eriksen on LinkedIn.
Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan Press On! has solved and always will solve the problems of the human race.

Research
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.
