 Course Time and Place: Mondays:    4:40pm - 6:20pm   in 1S-114 Wednesdays:   4:40pm - 6:20pm   in 1S-107

Textbook:  Introduction to Topology: Pure and Applied by Colin Adams and Robert Franzosa  Available at the University Bookstore or online.  ISBN: 0131-84869-0   ISBN 13: 978-0131-84869-6

Goals:  The primary goal of this course is to introduce you to topology, which is a major branch of modern mathematics.  Another goal is to learn how to do research in mathematics, including how to write concise but complete proofs, and how to present to others what you have learned.

Homework:  Assignments will be announced in class, sometimes referring to this website. Incomplete work with good progress will be rewarded. I highly recommend working jointly on homework problems with fellow students, but in the end you must hand in your own work.

Grading:  The course grade will be determined as follows:  homework and quizzes 40%,  midterm exam 30%,  final in-class presentation and written report 30%.

Help:  My office hours are on Mondays 3pm - 4:30pm, and Wednesdays 3:30pm - 4:30pm in my office, 1S-209.

Optimal Method of Study:  (1.) Come to class.  (2.) Read the relevant sections after class.  (3.) Do the homework. Leave time to think--do not put homework off until it is due!  (4.) Compare your solutions with other students to improve what you hand in.  (5.) Come to office hours with any remaining questions.
