**Instructor:**
Alvaro Pelayo, apelayo@math.wustl.edu

**Lectures:
** Monday, Wednesday, Friday 1-2pm, Room DUNCKER 101

** Office hours: ** Monday 4:30-5:30pm, Wednesday 10-11:30am

** Required Text: ** Theodore Shifrin, "Multivariable Mathematics. Linear Algebra, Multivariable Calculus, and Manifolds", John Wiley & Sons, 2005.

Other texts:

1. James R. Munkres, "Analysis on Manifolds", Addison-Wesley, 1991.

2. Michael Spivak, "Calculus on Manifolds: A Modern Approach to the Classical Theorems of Advanced Calculus", W.A. Benjamin, 1965.

** Grading: ** homework (15%), Midterm Exam 1 on Wednesday October 3 (25%), Midterm Exam 2 on Wednesday November 7 (25%),
cumulative Final Exam (35%) on December 19.
Exams will consist of a few theory questions, including definitions
and proofs of selected results, and some problems involving computations and proofs. There will
be no make-up exams - if you miss one midterm, the final exam counts 60%. If you take
both midterms and your grade
in the final is greater than your lowest midterm grade, then the grade in the midterm gets replaced
by the grade in the final. For example, if midterm 1 score is 80/100, midterm 2 score is 50/100 and final
score is 70/100, your score in the second midterm gets replaced by 70/100. If you choose to be graded "Pass/Fail",
a "Pass" grade reqires a grade of C- or higher.

** Homework: ** Assignments can be downloaded from this website, no paper copy will be given in class.
A grader will grade selected problems.
Discussing homework with others is ok. It is expected that everyone writes in his/her own words the homework solutions.
No late homework is accepted and the two lowest homework grades will be dropped (which can also count for
missing assignments).
Homework is due at the beginning of class on the due date.

** Prerequisites: ** Math 233 and Math 309 (not concurrent), or equivalent knowledge of matrix algebra and multivariable calculus.

** Syllabus ** (approximate): "Vectors and matrices. Continuity and differentiability of functions of several
variables. Partial derivatives, gradient. Maximum value theorem. Contraction
mappings." - as in (parts of) chapters 1-6 of the book.
Optional topics (time permitting) may include implicit function theorem, differential forms or integration.

** Tentaive outline: ** there will be no time to cover all of the sections in each chapter of Shifrin's book and not all sections will be covered
in the same depth. Class time is for the fundamental concepts of each chapter. Shifrin's book (and also the other books)
are sources for further explanations and examples. The following
is the approximate plan *subject to changes* (numbers refer to sections in Shifrin's book); this
plan will be updated as the course progresses.
