Numerical solution of differential equations is a fundamental course in numerical analysis, and it has broad applications in scientific computation, engineering science and et. al. The course will provide the basic concepts, theories and algorithms in numerical solution to differential equations, and these are the requisite for students to learn advanced numerical analysis and scientific computation.
This course consists of theoretical teaching and curriculum experiment. The main content of theoretical teaching is divided into two parts. The first part is devoted to numerical solution of ordinary differential equations (ODEs), which includes one-step methods, multi-step methods, numerical methods for stiff systems of ODEs, consistency, stability and convergence. The second part is followed by difference methods for the partial differential equations, including elliptic, parabolic and hyperbolic partial differential equations in one-dimensional space and two-dimensional space. The curriculum experiment is carried out with computer assistance, solving simple mathematical models and complex physical problems. Case teaching method is adopted to highlight independent learning and independent practice. It can stimulate students' learning initiative and awaken students' enthusiasm for learning.
Through the learning of this course, students majoring in computational mathematics are trained to have abstract thinking ability, logical reasoning ability and scientific computing ability. Enable students to understand the role of mathematics and solve practical problems. In this course, the instructor will cultivate students’ ability of scientific computing and solving practical problems, students' mathematical literacy in scientific research, and lay a solid foundation for students' future scientific research.
