Instructor Information

• Instructors: Gökhan Göksu

• E-mail: gokhan [dot] goksu [at] yildiz [dot] edu [dot] tr

• Course Web Site: gokhangoksu.github.io/MTM5101

General Information

• Schedule: Friday, 09:00-12:00

• Classroom: KMB-306

• Office Hours: Friday, 14:00-17:00 (and/or by appointment)

Expectations and Goals

• To understand the nature and to analyze the behavior of dynamical systems and to be able to apply these ideas to special systems. The aim is to teach students to apply these concepts to real-life systems they may encounter in the future.
