The aim of the course is to introduce, develop and discuss various methods of solving first, second and higher order ordinary and partial differential equations subject to a variety of boundary, initial and final conditions. The emphasis is always on the adaptation of the standard mathematical methods and techniques to their application in solving typical problems in physics and engineering. In this quest, this course extends, continues and builds on the material of the 1st part. Applications range from classical mechanics, hydrodynamics, electromagnetism and statistical physics through the quantum counterparts of these fields, and various engineering applications of these physics models, but also some less obviously related models such as variants of the predator-prey model in social economy and marketing.

Minimal Requirements

To pass the course with a grade B or better, a graduate Student must by the time of the final exam be able to demonstrate the ability to determine:

  1. solve ODEs using orthogonal polynomials and other special functions;
  2. use Sturm-Liouville theory to determine the Green’s function for any 2nd order linear ODE, and so solve inhomogeneous ODEs;
  3. solve integrals using the Gamma-function, its relatives and other special functions;
  4. use group theory and symmetries to characterize solutions of ODEs and PDEs, and simplify integration;
  5. solve typical problems involving random variables and probability.

A graduate student who cannot demonstrate the above listed skills by the time of the final exam automatically forfeits a grade of B or better — regardless of the total number of points acquired in homework, quizzes and exams.

Homework assignments (50 Shades of Hard)

Students are encouraged to start working —collaboratively— on the HW problems early, as a preparation for the exams

All written assignments (HW & take-home tests) are due by 12:00 am (midnight), end of the day indicated and should be sent by e-mail as single (bundled) PDF files; to this end, using a camera-to-PDF-scanner app on a smart-phone or tablet is highly recommended. Late homework will not be accepted, except in cases of documented emergency.

 

Other Matters

Collaboration Policy

Collaboration — but not blind copying — on the homework assignments is strongly encouraged; students should use this to learn from each other. There is no substitute for the diverse previous experiences and wealth of knowledge brought together by a cohort of students. All exams and quizzes are open text and open class-notes (including notebooks and class handouts), but no collaboration is allowed; by signing and submitting the exams and quizzes, the student vouches to have abided by this policy. Violation of this policy is covered under University regulations on academic dishonesty and cheating.

Presentation and Organization

First and foremost: your assignments are your communication to the instructor of the level of expertise to which you have mastered the subject matter covered in the course. So, while a neat presentation of home,- quiz- and exam-work is not required for full credit, it certainly makes it easier to assess the quality of the work and give the proper credit due. In all cases, include a simple sketch if it might help conveying the approach or the calculations. Where necessary, include all units and symbols such as the measure of an integral, arrow on a vector, vertical bars for the absolute value of a quantity, for the magnitude of a vector or for the determinant of a matrix, etc.

Each assignment is to be submitted (and is date-stamped) by e-mail (→ thubsch@mac.com), as a single PDF file. Handwritten and other “hard-copy” answer-sheets should be scanned and bundled into a single PDF file — there are many smartphone and tablet apps that do this automagically; some printers also include a flatbed scanner, if you prefer.

University Attendance Policy

Class Attendance Restricted to Registered Students: Only students whose names appear on the official course roster are permitted to attend class meetings. Students who are not registered are not permitted to attend or participate in course activities, do not have access to Blackboard, cannot submit course assignments, and will not receive a grade for this course. It is the students’ responsibility to ensure that they are properly registered by the published registration deadline. Requests to add courses after the deadline will not be considered.

ADA Procedures

Howard University is committed to creating an accessible, inclusive, and safe learning environment for all students and providing equal access to students with documented disabilities. Students seeking reasonable accommodation must first register with the Office of Student Services (OSS). There you can engage in a confidential conversation about the process for requesting reasonable accommodations in the classroom and clinical settings, which the Office of Student Services (OSS) determines. Accommodations must be requested each semester. Accommodations are not provided retroactively. If you want to request accommodations, please contact OSS via email at oss.disabilityservices@howard.edu or visit https://howard.edu/disability-services

Statement on Sex and Gender-Based Discrimination, Harassment and Violence

Howard University’s Policy Prohibiting Sex and Gender-Based Discrimination, Sexual Misconduct and Retaliation (aka, the Title IX Policy) prohibits discrimination, harassment, and violence based on sex, gender, gender expression, gender identity, sexual orientation, pregnancy, or marital status.
