### Syllabus

• Time and Place. TR 17:00-18:20, LART 308
• Instructor. Helmut Knaust, Bell Hall 219, hknaust@utep.edu, 747-7002
• Office Hours. TR 15:00-16:20, or by appointment.
• Textbook. Jerrold E. Marsden & Michael J. Hoffman, Elementary Classical Analysis, 2nd ed., W.H. Freeman and Co., New York.
• Prerequisites. MATH 3341 (Introduction to Analysis), or equivalent. The prerequisite material can be found for instance in: Edward D. Gaughan, Introduction to Analysis, American Mathematical Society; 5th revised edition, Ch. 0-5.
• Course Content. We will study the concept of a metric space. The rational numbers are dense in the set of real numbers: for every real number we can find a rational number arbitrarily close. If we want to consider the related question, whether and in what sense polynomials are dense in the set of continuous functions, we are naturally led to the general concept of the distance between two mathematical objects. A set with a distance function is called a metric space. In the first part of the course, you will learn about basic properties metric spaces might have, such as compactness, completeness and connectedness. As one of the most important examples of metric spaces we will then study the space of continuous functions with its notion of uniform convergence. One of the highlights of the course will be the proof of the Stone-Weierstrass-Theorem, which generalizes the result about polynomials mentioned above.
• Uniform approximation of a continuous function on a closed bounded interval by polynomials
• Tests. The two midterms will take place on Tuesday, October 2 and Thursday, November 8, respectively. The final on Tuesday, December 11, 16:00-18:45, is mandatory and comprehensive. The midterm exams will each count 25%, and the final 35%.
• Time Requirement. I expect that you spend an absolute minimum of six hours a week outside of class on reading the textbook, preparing for the next class, reviewing your class notes, and completing homework assignments. Not surprisingly, it has been my experience that there is a strong correlation between class grade and study time.
• Attendance. You are strongly encouraged to attend class. Students with six absences (excused or unexcused) will be dropped from the course with a grade of "F".
• Drop Policy. The class schedule lists Friday, November 2, as the last day to drop with an automatic "W". After the deadline, I can only drop you from the course with a grade of "F".
• Students with Disabilities. If you have a disability and need classroom accommodations, please contact The Center for Accommodations and Support Services (CASS) at 747-5148, or by email to cass@utep.edu, or visit their office located in UTEP Union East, Room 106. For additional information, please visit the CASS website at www.utep.edu/student-affairs/cass/.
• Academic Integrity. All students must abide by UTEP's academic integrity policies, see the Academic Integrity and Scholastic Dishonesty section of the website of the Office for Student Conduct and Conflict Resolution at www.utep.edu/student-affairs/osccr/. Please note that you may not leave the classroom during an exam.
