Course abstract

In this course the ordinary and partial differential equations are studied at advanced level. The course provides an understanding of the modern concepts and problems of mathematical modelling. It encourages mathematical thinking, and provides insight into various mathematical applications in information technologies and other fields. This course provides students with knowledge of construction of mathematical physics equations for description of the functioning of biological and other systems. Students will gain knowledge about formal solution schemes of equations and their realization on computer. In addition, students will acquire skills in working with appropriate software such as Matlab.
The course is interdisciplinary, it combines the fields of mathematics and physics – using physiscs and mathematics knowledge students learn to construct equations that describe real processes, as well as students learn methods to solve these equations.

Learning outcomes and their assessment

After successful completion of this course the student:
1. knows and is capable of proving knowledge and critical understanding of ordinary and partial differential equations, their applicability for describing the real-world processes considered in their specialty. – tests
2. is able to show understanding of relevant concepts and regularities, to perform necessary actions and operations. The student is able to use the appropriate software to make calculations. While working in a group or doing work independently, he/she is able to apply mathematical calculations corresponding to the problem of the specialty, to perform the intermediate results of the calculations and professional evaluation and interpretation of the final results, to apply knowledge in calculations for their branch of research, summarize and analytically describe the results, to evaluate the results of calculations in solving of mathematical physics problems. - independent works

Description of the organization and tasks of students’ independent work

The following independent works must be completed and credited, both in writing and using the appropriate application software:
1st Independent Work: Ordinary differential equations and their solvers
2nd Independent Work: Critical points. Phase plane analysis and construction
3rd Independent Work: Partial differential equations

Individual tasks must be completed and the software programs must be created for their computerized solution:
Individual Work No 1: Specific mathematical equation (parabolic, elliptical or hyperbolic)
Individual Work No 2: Application of the least squares method for approximation of given data.

Criteria for Evaluating Learning Outcomes

The test is accumulative, without additional knowledge testing, summarizing the results of the semester:
1. all tasks of independent works are accepted by the course lecturer (at least 80% of all tasks are correctly solved)
2. each test during semester is scored at least 4 points.
3. two individual tasks are fulfilled (according to the themes of the individual tasks, two programs have been created, which student can demonstrate and explain), each task is evaluated by 0-10 points. At least 50% of the maximum score must be collected.
The student may rewrite unsuccessfully written tests during the study process at the times indicated by the course lecturer.
Independent or individual works that are not accepted at a given time can be defended at the times indicated by the course lecturer.
