Prerequisites
The basic course of Mathematical analysis I-II is supposed, the knowledges of differential equations may be 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: illustration of applications of difference equations (problems from discrete mathematics, Fibonacci sequence, discretization of ODE, etc.).
• II. Difference calculus: differences, basic rules, differences of "composition" of sequences, differences of "elementary" sequences, differences of polynomials and transformation of polynomials from classical powers to generalized powers, discrete analogies of theorems from differential calculus (Bolzano, l'Hospital = Stolz- Cesaro) and their applications, discrete Taylor theorem.
• III. Summation calculus: summation, basic rules, summation of "elementary" sequences, definite sum.
• IV. Difference equations: equations of the 1st order and their applications, linear equations of higher orders (derivation of the form of the solution of a homogeneous equation, method of variation of constants, method of undetermined coefficients) and their applications.
