Topic 1: Selberg trace formula for compact hyperbolic surfaces. You should be reading the notes given out in our class.
Topic 2: Isoperimetric inequalities and estimates for low lying eigenvlaues of the Laplacian on bounded domains.
Topic 3: Resonances for Schrodinger operators: Definitions, Existence and the Counting Function.
Possible paper topics:
the Yamabe problem: Given a compact Riemannian manifold (X,g) in three or more dimensions, can one find a metric, conformal to g, with constant scalar curvature? see the review article by Lee and Parker
isopsectral sets for compact Riemann surfaces, especially the work of Osgood, Phillips, and Sarnack, see the review of Perry
Ray and Singer introduced a notion of analytic torsion for a compact, oriented Reimannian manifold and conjectured that it is equal to the Reidemeister-Franz torsion (a topological invariant). This conjecture was later proved independently by W. Muller and Cheeger.
MA 214 Section 002 Ordinary Differential Equations:
This is a basic course on ordinary differential equations (ODEs). There are three main components: 1) first-order ODEs and modeling (chapter 1-2), 2) second-order ODEs and applications to oscillators (chapter 3), and 3) the Laplace transform and applications to initial value problems.
Course Syllabus for MA214 002, Spring 2011. Lab office hours: Monday afternoon 4PM in CB 313. Wednesday afternoon in POT 753.
The final grades are posted. Good luck with everything and have a good summer! you can get copies of your final and the solutions are posted below.
This course has a computer lab component using a free software package called IODE developed at the University of Illinois by P. Brinkmann, R. Jerrard, and R. Laugesen. There will be four projects during the semester. No prior knowledge of MatLab is needed. IODE also runs on GNU Octave, a free software available at: http://www.gnu.org/software/octave/. I have not used it but there are comments about using Octave on the Illinois Iode web page.
You may now download IODE from the main IODE web page. The program works on 2007, 2008, 2009 and 2010 versions of Matlab. These are on the machines in Engineering and the library. The Save feature now works but it might still be more convenient to save your work as described next: ON SAVING GRAPHS: It is easiest to save your graphs as a Word document. This is convenient because you can put two graphs on one page and add comments! Enlarge the graph using the button on the upper right so it fills the screen. Press the "Print Screen" key on the keyboard. This copies the screen into a temp directory. Open Word and simply past the document into word. You can also type in your explanations, etc. you should then save the word document to your locker on the L-drive.
Instructions on how to start-up IODE using Matlab, Spring 2011
Open Lab Hours in CB313, Spring 2011. You may use the computers in the lab during any open lab hour. I will hold my office hour in CB 313 on Mondays 4-5 PM starting 31 January 2001. We can discuss the labs and homework.
Project 1: Due in class, Wednesday, 9 February 2011. You can use MatLab in the RG Anderson building computer labs, in the Science and Engineering Library lab (King South), and in CB 313 during open lab hours (schedule to be posted.) You cannot print in CB 313 so save your graphs in your locker using word, for example, and print them in another lab.
Comments on Project 1 compiled from reading the project reports. Please read through these comments and think about them as you do Project 2. GRADING: The lab was worth 15 points: the first ODE 3 points, and the remaining 3 ODEs were worth 4 points.

This will require us to study: oscillatory integrals, stationary phase, symbol calculus, basic properties of PsDOs (products, paramatrices), and basic Fourier integral operators.
MA 214 Section 003 Ordinary Differential Equations:
This is a basic course on ordinary differential equations (ODEs). There are three main components: 1) first-order ODEs and modeling (chapter 1-2), 2) second-order ODEs and applications to oscillators (chapter 3), and 3) the Laplace transform and applications to initial value problems.
NEW: Grades are posted. You may get a copy of your final by stopping by my office. The solutions are posted below. Have a good summer!
This course has a computer lab component using a free software package called IODE developed at the University of Illinois by P. Brinkmann, R. Jerrard, and R. Laugesen. There will be four projects during the semester. No prior knowledge of MatLab is needed. IODE also runs on GNU Octave, a free software available at: http://www.gnu.org/software/octave/. I have not used it but there are comments about using Octave on the Illinois Iode web page.
You may now download IODE from the main IODE web page. The program works on 2007, 2008 and 2009 versions of Matlab. The Save feature now works but it might still be more convenient to save your work as described next: UPDATE on SAVING GRAPHS: If the usual save button does not work, you can save to a Word document. This is convenient because you can put two graphs on one page and add comments! Enlarge the graph using the button on the upper right so it fills the screen. Press the "Print Screen" key on the keyboard. This copies the screen into a temp directory. Open Word and simply past the document into word. You can also type in your explanations, etc.

Open Lab Hours in CB313, Spring 2010. I will hold my office hour in CB 313 on Wednesdays 4-5 PM. We can discuss the labs and homework.
Lab 1: Introduction to IODE and the first project, Spring 2010
Project 1: Due in class, Friday, 5 February 2010. You can use MatLab in the RG Anderson building computer labs, in the Science and Engineering Library lab (King South), and in CB 313 during open lab hours (schedule to be posted.) You cannot print in CB 313 so save your graphs in your locker using word, for example, and print them in another lab.
Comments on Project 1 compiled from reading the project reports. Please read through these comments and think about them as you do Project 2. GRADING: The lab was worth 15 points: the first ODE 3 points, and the remaining 3 ODEs were worth 4 points.
Comments on Project 2 compiled from reading the project reports. Please read through these comments and think about them as you do Projects 3 and 4. GRADING: The lab was worth 15 points.
Course Material for Fall 2009:
MA 677 Real Analysis II:
This course is a continuation of Reals I taught in the spring of 2009. We will continue with the book of Stein and Shakarchi. You should be reading Chapter 6 on abstract measure theory. You should also be focussing on your paper and projects. Please see me to discuss them! A draft of you paper is due in class on 18 November 2009.
MA 214 Section 003 Ordinary Differential Equations:
NO LAB OFFICE HOUR Wednesday, 9 Dec. 3-4. There will be a review session Tuesday, 15 December, at 3 PM in 316 CB. Office Hour on Monday, 14 December 11 AM-12 PM and 4-5 PM in my office, 753 POT. ALL GRADES ARE FINAL (except the final exam grade and the lab 3 grade) AT 4PM TODAY UNLESS YOU CONTACT ME.
We have finished all the work for our course. In chapter 6, we did sections 6.1-6.5. We will begin to review for the final exam tomorrow, Wednesday. The final exam is scheduled for: Wednesday, 16 December, 10:30-12:30, in our classroom CB 203. It is worth 180 points. I will award everyone 15 points for the lab that we were not able to do. A practice exam is posted below and you may find other practice final exams posted in pervious versions of this course below (Remember: we did not do exact ODEs.)

Save your work as described next: UPDATE on SAVING GRAPHS: If the usual save button does not work, you can save to a Word document. This is convenient because you can put two graphs on one page and add comments! Enlarge the graph using the bottom on the upper right so it fills the screen. Press the "Print Screen" key on the keyboard. This copies the screen into a temp directory. Open Word and simply past the document into word. You can also type in your explanations, etc. Third project due date Friday, 4 December, in class. Please staple your pages together! CHANGE: Open lab in CB 313 on Wed. 2 Dec. from 3:15 - 4:00 PM only! You may turn in your projects on Monday.

Instructions on how to start-up IODE using Matlab, Fall 2009
Project 1: NEW! due in class, Wednesday, 23 September 2009 (read above). Try to get to CB313. Save you graphs in your locker using word, for example, and print them in another lab.
Comments on Project 1 compiled from reading the project reports. Please read through these comments and think about them as you do Project 2. GRADING: I will add 5 points to your score on Project 1 since it should have been worth 15 points.
