Course plan. Mathematical modeling
MMG510, MVE160
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.

Start working on Home assignment N1: 1) Find an example of non-linear ODE i
plane for each type of fixed points.
Calculate
eigenvalues
and separatrices in each case.
2)
Draw
phase protrait using Matlab (or by hand) for each of your
examples.
3) Try to find and
example of system with two different types of fixed points
OBS!!! Important to have a plan
for the project at the end of the second week.

Monday 15:15: Master equation for
chemical reactions. The Gillespie method. Paper by
Gillespie
Tuesday 15.15: Meetings on projects
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.
