Introductory course in linear algebra and differential equations 2019

The purpose of this course is to give a brief introduction to linear algebra and ordinary differential equations for incoming two year master students, who don't have the necessary backgrounds or wish a repetition of the subjects. The course is voluntary, but recommended. There is no exam, and no registration (just meet up to class).

  • 27. June 2019: Welcome to introductory course in linear algebra and differential equations. The course starts at 5th of August
