Learning Outcome

Knowledge:
 

  • Linear differential equations and thei relevant side conditions (e.g. boundary, initial)
  • Concept of ellipticity
  • Distributions and their convergence properties
  • Multiplication by smooth functions and derivatives of distributions
  • Fourier transform of distributions

Competences:

  • Understand the different realizations of differential operators on relevant function spaces

Type of assessment
Written assignment, Two 1 week take home assignments
Written examination, 3 hours under invigilation
The two written 1 week take home assignments count each 20% toward the final grade. The final exam counts 60%
Aid
All aids allowed

NB: If the exam is held at the ITX, the ITX will provide computers. Private computers, tablets or mobile phones CANNOT be brought along to the exam. Books and notes should be brought on paper or saved on a USB key.

Marking scale
7-point grading scale
Censorship form
External censorship
Re-exam

Same as ordinary exam. If one of the assignments or both received a failing mark (i.e., less than half the maximal number of points for the assignment) before the ordinary exam it (or they) can be resubmitted no later than two weeks before the beginning of the re-exam week. If an assignment is resubmitted it will be the resubmitted assignment that will count towards the grade.

Criteria for exam assesment

The student must in a satisfactory way demonstrate that he/she has mastered the learning outcome.
