AS/SC/MATH4000 3.0 FW and 6.0 Y
Individual Project

1998/99 CALENDAR COPY:A project of a pure or applied nature in mathematics or statistics under the supervision of a faculty member. The project allows the student to apply mathematical or statistical knowledge to problems of current interest. A report is required at the conclusion of the project.

The student works under supervision of a faculty member, who is selected by the Course Coordinator and the student. The project allows the student to apply mathematical or statistical knowledge to problems of current interest. A report is required at the conclusion of the project.

Students in the Applied Mathematics Honours Programmes are particularly encouraged to take this course. The procedure is as follows: Each year, faculty members who are interested in supervising projects will submit project descriptions to the Course Coordinator for Applied Mathematics. Students will meet with the CC for AM, and they will jointly decide on a faculty member to supervise the project, taking into account the background and interests of the student, as well as the availability and interests of faculty members.

The amount of work expected of the student is approximately ten hours per week, that is, the equivalent of a standard full-year (for 4000 6.0) or half-year (for 4000 3.0) course. The supervisor is expected to spend about one or two hours per week with the student, averaged over the duration of the project. In addition to the final report, regular short progress reports will be expected at definite times during the course. The final grade will be based upon the final report as well as the interim progress reports.
Applied Mathematics Coordinator: Martin Muldoon
Maths. for Commerce Coordinator: Morton Abramson
Pure Mathematics Coordinator: Walter Whiteley
Statistics Coordinator: Augustine Wong

Prerequisites: May be taken for major credit by students in Honours Programmes in Applied Mathematics, Mathematics, Mathematics for Commerce, and Statistics. Permission of the appropriate Coordinator (above) is required. Applied Mathematics students can enrol only after they have completed the core programme in Applied Mathematics.

Topology

1998/99 CALENDAR COPY:Topological spaces, continuity, connectedness, compactness, nets, filters, metrization theorems, complete metric spaces, function spaces, fundamental group, covering spaces.

Topology is a large and core branch of modern mathematics (along with geometry, algebra and analysis). Major parts of it can be viewed as a synthesis of geometry and analysis, strongly influenced by algebraic methods. Other components can best be described as point-set topology and will offer some insight into modern set theory. Its study clarifies the nature of concepts learned in analysis and geometry such as proximity, continuity and distance. It studies objects called topological spaces by studying the maps (functions) that they support, and their invariants.

More advanced topics in topology that this course leads to are point-set topology, algebraic topology (homology theory, homotopy theory) and differential topology (manifold theory). Topology has many applications within mathematics, but nowadays it also is used in physics and physical astronomy (e.g. cosmology) as well as in catastrophe theory and physiology, economics and sociology.

The text will be C. Wayne Patty, Foundations of Topology (Waveland Press, ISBN 0-88133-955-5).

The final grade will be based on assignments (20%), class tests (40%), a project (10%) and a final examination (30%).

The course can be used to fulfill the Pure Mathematics Honours requirement.

Topics in Number Theory:
Algebraic Number Theory

(Note: MATH4140 3.0 is offered on an irregular basis. Subject to approval by the Faculty of Arts, it will be offered in the fall.)

1998/99 CALENDAR COPY:The course covers prime numbers, modular arithmetic, Diophantine problems, cryptography and, possibly, some other contemporary applications.

Number theory is an old branch of mathematics and its content is vast. We shall focus on topics in the direction of algebraic number theory. In short, this theory can be described as the study of the divisibility properties of integers. Since every integer can be factored into a product of primes, the prime numbers are of the utmost importance in the theory.

We shall begin by discussing prime numbers and modular arithmetic. We shall also study Diophantine problems, that is, integral solutions of polynomial equations with integer coefficients. This introduction to the classical theory will be followed by some contemporary applications. In particular, we shall study some elementary cryptography.

AS/SC/AK/MATH4430 3.0 W
Stochastic Processes II

(same as GS/MATH6602 3.0) 1998/99 CALENDAR COPY:Continuous parameter stochastic processes: Markov jump processes,
Poisson processes, renewal theory. Topics from queuing theory,
Brownian motion, stationary processes.

This course is an introduction to stochastic, or random, processes. Stochastic processes are models which represent phenomena that change in a random way over time. Simple examples are (a) the amount of money a gambler has after each play of a game and (b) the number of people waiting for service at a bank at various times. This course studies some of the most basic stochastic processes, including Markov chains and Poisson processes. A Markov chain is a stochastic process in which predictions for the future depend only on the present state of affairs, but not on knowledge of the past behaviour of the process. Markov chains are relatively easy to analyze, and they have been used as models in many areas of science, management, and social science. A Poisson process is a model for the occurrence of random events (such as oil spills in the Atlantic Ocean). This course will treat both the theory and applications of these stochastic processes.

Prerequisite: AS/SC/AK/MATH2030 3.0
or AS/SC/AK/MATH3030 3.0.

Coordinator: T.B.A.


AS/SC/MATH4630 3.0 W
Applied Multivariate
Statistical Analysis

(same as GS/MATH6625 3.0) 1998/99 CALENDAR COPY:The course covers the basic theory of the multivariate normal distribution and its application to multivariate inference about a single mean, comparison of several means and multivariate linear regression. As time and interest permit, further related topics may also be covered.

We will study methods of analysis for data which consist of observations on a number of variables. The primary aim will be interpretation of the data, starting with the multivariate normal distribution and proceeding to the standing multivariate inference theory based on linear models. Sufficient theory will be developed to facilitate an understanding of the main ideas. This will necessitate a good background in matrix algebra, and some knowledge of vector spaces as well. Computers will be used extensively, and familiarity with elementary use of SAS or S+ will be assumed. Topics covered will include the multivariate normal population, inference about means and covariance, multivariate linear models, principal component analysis, , and some discussion of canonical correlation analysis, discriminant and classification, factor analysis and cluster analysis, as time permits.

Grades will be based on a combination of class quizzes and a final examination, plus homework including a group project. The coordinator may permit students to enrol who have background ``equivalent to'' the formal prerequisites below.

Prerequisites: AS/SC/AK/MATH3131 3.0;
AS/SC/MATH3034 3.0 or AS/SC/MATH3230 3.0;

AS/SC/MATH4730 3.0 F
Experimental Design





(same as GS/MATH6626 3.0) 1998/99 CALENDAR COPY:An examination of the statistical issues involved in ensuring that an experiment yields relevant information. Topics include randomized block, factorial, fractional factorial, nested, Latin square and related designs. Further topics as time permits. The emphasis is on applications.

Good experimental design is the cornerstone for the generation of good data. It can be viewed as selecting the best feasible experiment to achieve some specific objective. This includes the choice of treatments, and the random allocation of experimental units to them. Method of estimation is an important component of the determination of a design. One must consider how the data will be analysed after the experiment is carried out and data are collected. With the analytical procedure in mind, a proper choice of experiment is then determined to achieve that goal.

Various designs will be discussed in this course through definition of objectives, analytical procedures, and feasibility of experimental constraints.
