Lecture (by Kwak)
Recitation by Teaching Assistant
We are learning a basic concept of linear algebra with some applications. The basic synopsis of this course are basic properties of Matrices and Determinants, Vector spaces, linear transformations, Inner product spaces, Diagonalizations, Complex matrices, If allowed, elementary practice for Jordan Canonical forms including several decompositions of matrices. THE CLASS WILL BE TAUGHT IN ENGLISH.
No special prerequisite beyond the basic algebra in high-school level. There should be no absence in class since preparations and reviews are important to go through this course successfully. Without a prior approval, more than FIVE times of absence in class will make F grade unless a student withdraws it. Quiz, about 10-15 minutes exam., will come up in class without any early notice.
Course Evaluation Criteria
Midterm Exam I (100 minutes) 25% will be held on Oct 8 (Tuesday)
Midterm Exam II (100 minutes) 25% will be held on Nov 26 (Tuesday)
