Introduction to Mirror Symmetry and the Fukaya Category
Abstract:
I shall give an overview of recent progress in
Homological mirror symmetry both in clarifying our conceptual
understanding of how the sign of the canonical bundle affects the
behaviour of the mirror, and in obtaining concrete examples where the
mirror conjecture has now been verified.
A series of 10 hours of lectures, 1422 July 2010

in Napier G04 in the Napier building on the main campus.

Dirac Operators in Geometry, Topology, Representation Theory, and Physics
Abstract:
Dirac introduced his eponymous operator to describe electrons in quantum
theory. It was rediscovered by Atiyah and Singer in their study of the index
problem on manifolds. In these lectures we explore new theorems and
applications. Several of these also involve Ktheory in its recent
twisted and differential variations.
A series of 10 hours of lectures, 1822 October, 2010.
10:00 am12:00 am, October 18, 19, 20, 21, 22, 2010.
In Conference Room 7.15, Level 7,
Innova 21 building on the main campus
(see the map).
Titles of individual lectures:
Introduction to twisted Ktheory:
After a review of standard Ktheory I will discuss the twisted form and
some properties. Then I will compute twisted K_G(G) in some cases.
Loop groups and Dirac families:
I will describe the finite and infinitedimensional versions of the
construction which yields my theorem with Hopkins and Teleman. This
will include some generalities about loop groups and their
representations.
A TQFT from twisted Ktheory:
I will discuss TQFTs in general and give some examples, etc.
I will show how to construct the ring structure on twisted K_G(G).
Differential Ktheory and the AtiyahSinger theorem:
An introductory lecture on differential cohomology theories in general
and differential Ktheory in particular. Then the differential index
theorem with Lott.
Anomalies and "categorified" index theorems:
A general lecture on some physics, then some discussion of anomalies in
supersymmetric quantum mechanics and on the worldsheet of string
theory.
