Doctor of Philosophy in Applied Mathematics - Dynamical Systems and Ordinary Differential Equations
關於課程
Dynamical systems problems range from the vibrations of molecules to planetary motion and span the breadth of the physical, biological and social sciences as well as engineering. Research in the subject stretches from investigation of realistic models of complex systems like the brain and the power grid to mathematically rigorous investigations of highly abstract systems such as the iteration of quadratic functions. In the past few years, CAM faculty and students have used dynamical systems to study the oscillations of bubbles, the flight of mosquitoes, the emergence of cooperation, and rapid evolution in predator -prey systems, among other phenomena. Cornell has a long history as a center for research in the subject, and CAM has been a focal point for that research. CAM faculty who regularly teach dynamical systems courses and serve as advisors of students doing research in the subject are Steve Ellner, John Guckenheimer, John Hubbard , Richard Rand, James Sethna, John Smillie, Paul Steen, Steve Strogatz, Alex Vladimirsky and Jane Wang. Many students have taken advantage of the interdisciplinary opportunities provided by CAM to engage in research that connects experiment, theory and simulation.

如何申請
Entry requirements for 康乃爾大學
You will be asked to enter typical application information such as nationality, GPA, schools attended, etc.
You will be required to upload an accurate unofficial transcript for each school you have attended. Please do not send official copies to the CAM office. Please note that there are only up to three fields for listing schools attended. If you attended more than three, you must upload those transcripts in the writing sample portion of the application.
If you have appropriate supplemental documents such as an undergraduate research paper, awards, etc., upload them in the writing sample portion of the application.
A statement of purpose is required and can be uploaded directly into the application.
At least three letters of recommendation are required. Additional letters are allowed. Recommenders may submit their letters online. Once an application is submitted, recommenders receive an automated email soliciting their letter (you will be prompted to provide their contact information before you submit your application).
Submitting GRE scores is optional. The GRE subject test in mathematics is also not required, but it is particularly useful for applicants for whom math is a secondary field at the time of application. (The University code is 2098, if submitting scores.)
Official TOEFL scores are required from international applicants. The Graduate School's policy is that there are minimum scores for each section (a cumulative score is not an accurate measure of English proficiency and is not sufficient for an offer of admission):
Writing ? 20, Listening ? 15, Reading ? 20, Speaking ? 22
The TOEFL is not required of applicants who have studied full-time for two or more years at a college or university where English is the language of instruction and the college or university is located in a country where English the primary language. Applicants from countries where English is the primary language are also exempt. However, it is very important you check with the CAM program office or the Graduate School to determine if your country applies. For example, applicants from Anglophone Canada and New Zealand are exempt. Applicants from Nigeria, Singapore and the Quebec province of Canada are not exempt. The University code for reporting is 2098.
IELTS: The Graduate School requires an overall band score of a 7.0 or higher on the IELTS. Please email gradadmissions@cornell.edu for information about how to send your scores.
The Graduate School requires an application fee of $105. A fee waiver request will be considered if this fee presents a financial hardship. See Application Fees for instructions on how to submit a waiver request.
Applicants who are non-US citizens may be contacted via email 1-3 weeks after the application submission deadline to participate in a brief, conversational English video interview (no specialized knowledge necessary). Though not all non-US-citizen applicants will be required to participate in this interview, definite exceptions include citizens of Australia, Canada (except Quebec), Ireland, New Zealand and the United Kingdom.
Cornell University expects all applicants to complete their application materials without the use of paid agents, credentials services, or other paid professional assistance. The use of such services violates University policy and may lead to the rejection of application materials, the revocation of an admissions offer, cancellation of admission, or involuntary withdrawal from the University.
University minimums for the iBT version of the TOEFL are: Writing, 20, Listening, 15, Reading, 20, Speaking, 22. You must receive the minimum score on each subsection.
