Course plan. Mathematical modeling MMG510, MVE160

spring 2011.


Teaching will include lectures, exercises, 2 assignments to be done at home and giving two bonus points each, and a large project done in working groups.

We will study during 8,5 weeks and have lectures and exercises on Mondays at 10.00 in MVF31 and on Thirsdays in  MVF31 at 8.00.

On Tuesedays at 15:00 in MVF31 we will have lectures and exercises during first two weeks and later we will have discussions on the projects at this time.

One meeting per week with each working group for discussing the projects must  take place at the Mathematical Center.

The weeks 21 will be devoted to the presentation of projects 30 minutes for every group. A working group can consist of maximum 3 people.

A written examination over the theoretical part of the course will take place at the end.

Well done home assignments will be counted as a bonus for the corresponding part of the written examination.

Total points for the course will be an average of points for the project (60%) and for the examination (40%).
The textbook for the course is: Arrowsmith D.K. , Place C.M.: Ordinary Differential Equations.
 A Qualitative Approach with Applications. Chapmann and Hall. (1982).The reference to the book below is
A.P.
The order of chapters can be slightly shifted.

week 14 (III) ()

       Tuesday  15.15:  Meetings on projects

       Thirsday   8:00: - Monte Carlo methods for integral equations.  LectureMonteCarlo .   

week 15 (IV) ()

     Start working on Home assignment N2 :

    1)  Choose a "chemical system" with two types of particles such
         that the corresponding ODE in plane has a polynomial right hand side and a stable fixed point

   2)  Write a code in Matlab that solves the ODE and draw some typical trajectories.
   3)  Model the same system by Gillespie method and compare random trajectories with those you got from ODE.
   4) Scale up the system of ODE ( 100 or 50 times ) intorducing fro example new X=100 x and new Y=100 y.
       One can see that coefficients for linear terms will be the same. Coefficients at quadratic terms will become 100 smaller and
      coefficients at cubic terms will become 10000 smaller. 
  5) Solve the scaled up system with both methods again and observe that random trajectories look very much like ODE solutions.
