Prerequisite: Registration as a graduate student in the Department of Mathematics and Statistics, or MATH 3F03, or permission of the instructor. M3A03 is recommended.

Brief Course Description: This is an introductory course in Delay Differential Equations with Applications. Delays must be taken into consideration in mathematical models, since they occur naturally in applications, ranging from population biology, epidemiology, economics, and neural networks, to the control of mechanical systems. We will discuss both Distributed Delay (Integro-Differential Equations) and Discrete Delay (Functional Differential Equations), with emphasis on the latter. Ideal prerequisites for this course include a course in the qualitative theory of ordinary differential equations (e.g. M3F03 or M741), calculus of several variables, and some basic analysis and linear algebra. Students will study the basic theory (including existence, uniqueness continuous dependence), study the properties of solutions of linear and nonlinear equations (including exponential solutions, growth estimates, Laplace transforms, stability analysis, and bifurcation analysis). They will thus learn the key tools necessary to understand the applications literature involving delay differential equations and to construct and analyze mathematical models involving (systems of) delay differential equations, both analytically and numerically.

Format: A combination of formal lectures by the instructor, lecturing by the students, and projects. There will also be assignments and computer lab work.

Projects: Individual projects adapted to meet the individual interests of the students comprising of both oral and written components.

Absences and missed work: If you are absent from the university for a minor medical reason, lasting fewer than 5 days, you may report your absence, once per term, without documentation, using the McMaster Student Absence Form. Absences for a longer duration or for other reasons must be reported to your Faculty/Program office, with documentation, and relief from term work may not necessarily be granted. When using the MSAF, report your absence to course_email@mcmaster.ca. You must then contact the instructor immediately (normally within 2 working days) by email (see above for contact information) to learn what relief may be granted for the work you have missed, and relevant details such as revised deadlines, or time and location of a make-up exam. Please note that the MSAF may not be used for term work worth 30% or more, nor can it be used for the final examination.

If you must miss a lecture, it is your responsibility to find out what was covered. The best way to do this is to borrow a classmate’s notes, read them over, and then ask your instructor if there is something that you do not understand.

Late Work: All assignments are due in class on the specified date, prior to class, unless otherwise stated. I reserve the right to penalize late work by 10% per day.

Academic Dishonesty: Academic dishonesty consists of misrepresentation by deception or by other fraudulent means and can result in serious consequences, e.g. the grade of zero on an assignment, loss of credit with a notation on the transcript (notation reads: "Grade of F assigned for academic dishonesty"), and/or suspension or expulsion from the university.
