Course Syllabus


The course is focused on first-year students of the Economics and Management of the International Bachelor's in Business and Economics. The goal of the course is to study basic concepts, learning the basic methods of Linear Algebra and their application for the construction of economic and mathematical models. The course studies the theory of matrices and determinants, the structure of solutions to systems of linear algebraic equations, linear spaces, Euclidean spaces, the theory of self-adjoint operators and the second order curves.
Learning Objectives

Learning Objectives

  • The objectives of learning the course "Linear Algebra" are the study of units of Matrix Algebra, the solution of systems of Linear Equations and Vector Analysis, allowing the student to navigate in such courses as "Probability Theory and Mathematical Statistics", "Methods of Optimal Solutions", "Mathematical Models in Economics". The course "Linear Algebra" is used in the theory and applications of multivariate mathematical analysis, differential equations, mathematical economics, econometrics. The content of the course can be used to design and apply numerical methods for solving problems from many areas of knowledge, for constructing and researching mathematical models of similar problems. The discipline is a model applied apparatus for studying the mathematical components of professional education of students of the Economics and Management.
  • 1. know the Matrix Equations solving theory, the fundamentals of Vector Analysis and Analytical Geometry
  • 2. be able to apply the linear algebra tools in the forming of economic models and solving of applied problems used in the courses "Mathematical Models in Economics" and "Game Theory"
  • 3. have skills in solving systems of linear equations and constructing diagonal quadratic forms
