Prerequisites
The basic course of Mathematical analysis I-II is supposed, the knowledges of differential equations are useful.
Course Enrolment Limitations
The course is also offered to the students of the fields other than those the course is directly associated with.
fields of study / plans the course is directly associated with
Course objectives
The aim of the course is to present the basic facts of the theory of difference equations.
Learning outcomes
Students will know applications of difference equations and understand theoretical and practical methods for their solution. Students will be able to compare the differences in the theories of differential and difference equations and, in particular, understand the differences which arise in these theories.
Syllabus
• I. Introduction: motivation, elements of the diference calculus, elementary recursions.
• II. Linear difference systems: homogeneous and nonhomogeneous systems, variation of parameters, transformations of difference systems, higher order linear difference equations.
• III. Stability of difference equations and systems: motivation, dynamics of first order difference equations, stability of linear equations and systems.
• IV. Oscillation theory of difference equations: Sturm-Liouville second order difference equation, methods of discrete oscillation theory, symplectic difference systems, difference equations and orthogonal polynomials.
