3. Linear programming:
basic properties and examples of linear programs; basic solutions; the fundamental theorem of linear programming; the simplex method; dual linear programs.
4. Differential equations:
Constant coefficient linear differential equation (ODE) systems, fundamental matrix; qualitative solution: phase portrait diagrams; nonlinear systems; fixed points; linearization of dynamic system in the plane.
5. Difference equations:
review of difference equations; linear difference equations; non-linear difference equations and phase diagram; first order difference equations systems.
6. Optimal control:
maximum principle; transversality conditions; transversality conditions in infinite horizon problem; second variations and sufficient conditions.
7. Dynamic programming:
dynamic programming problems; the principle of optimality; the value function; Bellman equation; Euler equations.
8. Stochastic processes:

Type of course
A student should be able to:
- solve constrained optimization problems,
- solve simple differential and difference equations,
- analyze nonlinear differential and difference equations and systems of equations,
- solve and analyze optimal control problems,
- use the above techniques in economic modeling and finance.
To complete the course, the student has to complete the assignments, pass the midterm exam and pass the final exam. The passing threshold is 50%.
During the midterm and final exam student will have to solve by hand five problems.
Additionally, there will be home assignments. A student will be asked to solve some problems from economics and finance in each homework.
There will be no oral exams.
The final grade will be determined as follows:
Midterm Exam - 30%, Final Exam - 50%, Assignments - 20%.
