Math 595 Section CAP/TRA (Introduction to Linear Analysis) Fall 2005

This course will treat the fundamentals of analysis and (linear) algebra in normed vector spaces. Its purpose is to provide students with a firm background in basic concepts which undergird modern analysis: metric and topological spaces, normed and topological vector spaces and linear algebra, differential calculus in normed linear spaces. Applications (existence and uniqueness theorems for ODE's, fixed point theorems, ...) are numerous and will figure prominently.

• Homework and projects: There will be regular homework assignments, due each Monday. In addition, there will be three extended assignments/projects, one for each of the three parts of the course. Each project will be due approximately 1-2 weeks after we complete the corresponding part of the course. You are encouraged to work on the homework and projects in groups, although each student should submit a separate set of solutions. (Please indicate which other students you collaborated with, if any.)

• Exams: There will be two one-hour midterm exams (in class) and a cumulative final exam. Some of these exams may be takehome exams.

• Grading Policy: Grades will be computed according to the following percentages:

  Homework	25%
  Projects	10%
  First Midterm	20%
  Second Midterm	20%
  Final	25%
