Math 497C - Honors MASS Geometry

Lie Groups in Two, Three and Four Dimensions

Instructor:  Nigel Higson, Evan Pugh Professor of Mathematics
Teaching Assistant:  Qijun Tan

113 McAllister Building,  MWRF 10:10 - 11:00 a.m.

Description:  Lie groups arise from the continuous symmetries that are seen in nature and mathematics. Sometimes the symmetries are easy to appreciate (such as the continuous rotational symmetries of a circle, as opposed to the discrete, 3-fold rotational symmetries of an equilateral triangle) and sometimes they are not. This course will given an introduction to the theory of Lie groups, with an emphasis on examples in low dimensions, where many of the most interesting applications to mathematics and physics are to be found. Topics will include the basic properties of matrix Lie groups, Lie algebras and the exponential map; examples from real Euclidean space, complex Hermitian space, the quaternions and the octonions; the mechanics of rotating bodies; complexification; representations; applications to spin, the eightfold way, Lorentz transformations, and other things.

Objectives:  The first objective of the course to will to teach the basic theory of Lie groups and Lie algebras. Beyond that, the course will present many examples where mathematical techniques from geometry, algebra, analysis and combinatorics interact with on another, and contribute to our understanding of the laws of nature.

Reading:  No textbook will be used. Readings will be suggested by the instructor, and lecture notes will be developed and distributed as the course progresses.

Math 497B - Honors MASS Analysis

Classical Mechanics and Calculus of Variations

Instructor:  Mark Levi, Professor of Mathematics

113 McAllister Building,  MWRF 11:15 a.m. - 12:05 p.m

Description:  Classical mechanics and calculus of variations lie at the foundation of the modern theory of dynamical systems. This is the field where geometry, differential equations and number theory interact with each other and with physics. I will describe examples of this interaction, along with the fundamental concepts and ideas of the subject, with numerous special examples and with many entertaining problems.

Objectives:  I would like to give a clear intuitive understanding of the subject of classical mechanics and of calculus of variations, and to show how many ideas that appear mysterious or arbitrary are actually very natural and simple, if looked at in the right way. We will also solve many intuition-enhancing problems.
