- [AP] Simon, Blume: Answers Pamphlet for Mathematics for Economists. Available as pdf in It's Learning, contains solutions for problems in the textbook [ME].
- [LSGE] Eriksen: Linear Systems and Gaussian Elimination, Handout, 2011. Available as pdf for download, covers part of the course, which is also covered in the textbook [ME].
- [M] Eriksen: Matematikk for økonomi og finans, Cappelen Damm 2016 (in norwegian). Textbook for the mathematics course at BSc/undergraduate level at BI, covers the material from the preparatory course FORK 1003.
- [FMEA] Sydsæter, Hammond, Seierstad, Strøm: Further Mathematics for Economic Analysis, 2nd Edition, Prentice Hall 2008. Recommended reading, used at textbook in GRA 6035 Mathematics earlier.
- Strøm, Sydsæter, Seierstad, Hammond: Student's Manual for [FMEA]. Solutions to selected problems (marked SM = Student Manual) in [FMEA].
- Eriksen, Gustavsen: GRA6035 Mathematics. Available as pdf for download. Lecture Notes for GRA6035 Mathematics used in 2009-2010 (including Problems and Exam Problems with Solutions).

All material covered by the lectures and problems is part of the curriculum for GRA 6035 Mathematics, and is relevant for the final exam. All material covered by Lecture 1-6 and all problems corresponding to these lectures is relevant for the midterm exam. The list of sections in [ME] in the Lecture Plan below is indicative of the curriculum of the course.

In the office hours, you can ask me for help with problems or ask other questions from the lectures. It is not necessary to make an appointment to see me in the office hours. It is often possible to see me outside office hours (come by to see if I am available, or make an appointment). I will be in my office most of the time Mon-Fri, except Thu 08-11 when I teach another course.

The lecture plan is tentative, and may be changed/updated during the semester. In some cases, only parts of the sections indicated in the Reading column is required for this course (material in parantheses is not core material, but still useful to read to link the mathematics in the course to applications). Lecture notes will be uploaded as they become available (typically soon after the lecture).
