Differential equations are utilized to analyze the mathematical structure of nonlinear phenomena, In this lecture we introduce methods to handle differential equations. In the first half of lectures, we study basic theories such existence theorem. In the second half, we study more advanced theories to analyze the large time behavior of solutions.
In this lecture, we study the basic concepts and methods to study the mathematical structure of nonlinear phenomena, We show the existence of solutions to ordinary differential equations. Then we discuss asymptotic analysis, bifurcation theory and limit cycle as special topics.
