My recent research has focussed on three areas: random Schrodinger operators, geometric analysis of real and complex hyperbolic manifolds, and resonance and eigenvalue estimates. My research is partially supported by the National Science Foundation DMS. My current doctoral students are Joseph Lindgren and Robert Wolf.

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.

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.

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.
