Course description and aims

After introducing some terminology and fundamental notions on differential equations, we explain elementary method for explicit solutions, general method for solving constant coefficient linear differential equations and some analysis on linear differential equations. This course is to be continued to Differential Equations II.


Differential equations are fundamental notions appearing in all fields of mathematics. Space of solutions have algebraic structure, existence theorems of solutions give various geometric and analytic objects of great interests. This course is an entry to these paths.

Student learning outcomes

Main topic of this course is a basic theory and its applications of ordinary differential equations of one unknown variable. Ordinary differential equations describe various natural phenomena and physical laws, thus, method of solving equations and its theory are important mathematically as well as for applications. Students are expected to master method of solving differential equations, and to understand the theory to derive properties of solutions.

Keywords
