determinants and matrix inverses; Cramer’s rule; rank of matrix; linear systems of equations; degrees of freedom; eigenvalues; quadratic forms.

2. Non-linear programming:

constrained optimization; equality constrains and the Lagrange problem; the constraint qualification; Lagrange multipliers; Kuhn-Tucker multipliers.

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

## Course coordinators

## Mode

## Learning outcomes

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.

## Assessment criteria

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%.
