MAT498
Undergraduate Thesis I
4.00
Undergraduate
Compulsory course for BSc (Research) Mathematics. Prerequisites: None. Overview: At the beginning of the 7th semester, the student must select and gain the consent of a project supervisor (from the faculty of the Department of Mathematics). If the student is unable to fix a supervisor, the Department Undergraduate Committee will arrange one. The supervisor will help the student in deciding the structure of the project and identifying reading material and other resources. MAT498 is intended for preparation and initial work for the student's undergraduate thesis, which culminates with MAT499 Undergraduate Thesis II.

Compulsory final semester course for BSc (Research) Mathematics. Prerequisites: MAT498 Undergraduate Thesis I. Overview: The course can take a variety of forms, from a reading course on advanced topics to computational work in an application of mathematics. The work will be presented in a public seminar at the end of the academic year. Details: The student must select and gain the consent of a project supervisor (from the faculty of the Department of Mathematics) by the end of the first week of his/her seventh semester. If the student is unable to fix a supervisor, the Department Undergraduate Committee will arrange one. The student will begin work during the seventh semester by registering for MAT498 Undergraduate Thesis I. The supervisor will help the student in deciding the structure of the project and identifying reading material and other resources. While the supervisor will help and encourage the student, successful completion of the project is the student’s responsibility. Credit will be given for independence and initiative in identifying resources and topics. The project will conclude with the submission of a written report (dissertation) and a public presentation of the work done. The dissertation should be a detailed exposition of the work done, including a literature review as well as specific investigations. It should be typeset using LaTeX/MS Word.

We will also learn approximation techniques which will be needed in cases where it is impossible to get analytical solutions.

Credits: 4 (3 lectures and 1 tutorial weekly) Prerequisites: MAT 360 Linear Algebra II for undergraduates, MAT 660 Linear Algebra for graduate students Overview: This course provides a bridge to modern geometry. It provides a unified axiomatic approach leading to a coherent overview of the classical geometries (affine, projective, hyperbolic, spherical), culminating in a treatment of surfaces that sets the stage for future study of differential geometry. Detailed Syllabus: Affine geometry – finite planes, planes over fields, affine transformations, collineations, affine coordinates, triangles and parallelograms, classical theorems of Menelaus and others. Projective geometry – finite planes, projective completion of affine planes, homogeneous coordinates, projective transformations, collineations, projective line, poles and polars. Conics – affine and projective classifications, group actions. Euclidean geometry – isometries, triangles, parallelograms, length minimizing curves, geometry of plane curves. Hyperbolic geometry – Poincare upper half plane, Poincare metric, distance function, triangles and area, two-point homogeneity. Spherical geometry – Sphere, tangent space, great circles, triangles and area, two-point homogeneity Surfaces – Level surfaces, parametrized surfaces, curvature, Gauss theorem, introduction to manifolds.   References: An Expedition to Geometry by S Kumaresan and G Santhanam.

Credits: 4 (3 lectures and 1 tutorial weekly) Prerequisites: MAT 621 (Analysis I) or MAT 332/432 (Geometry of Curves and Surfaces) Overview: Differential Geometry generalizes the calculus of several variables on Euclidean spaces to `differential manifolds’. This enables the use of analysis and linear algebra to study geometry. The two highlights of this course are the study of Lie groups and of differential forms, with the latter leading to the general Stokes’ theorem in integration. Detailed Syllabus: Part 1: Calculus in Rn Rn as a normed linear space, derivative, chain rule, mean value theorem, directional derivatives, inverse mapping theorem, implicit function theorem, immersions and submersions, integration, higher derivatives, maxima and minima, existence of solutions of ODE. Part 2: Differential Manifolds and Lie Groups Differential manifolds, smooth maps and diffeomorphisms, Lie groups, tangent spaces, derivatives, immersions and submersions, submanifolds, vector fields, Lie algebras, flows, exponential map, Frobenius theorem, Lie subgroups and subalgebras. Part 3: Differential Forms and Integration Multilinear algebra, exterior algebra, tensor fields, exterior derivative, Poincare lemma, Lie derivative, orientable manifolds, integration on manifolds, Stokes' theorem.
