Topic and Speakers
Introduction to noncommutative geometry in string and field theory
Chong-Sun Chu (Durham)
I will start with a basic introduction to D-brane and explaining how noncommutative geometry arises
in string theory. Then we will explore the properties of noncommutative field theory. The emphasis
will be on the novel aspects in contrast to the usual local quantum field theory. Applications of
noncommutative geometry to other areas such as tachyon condensation and AdS/CFT will be discussed.
Introduction to matrix model and non-critical string theory
Akikazu Hashimoto (Wisconsin)
In these lectures, I will review Liouville theory as string theory in non-critical dimensions, matrix
model formulations of these string theories, and recent developments in supersymmetric non-critical
string theories and D-branes. Topics will include ground ring relations, large N techniques, integrability,
FZZT and ZZ branes, open/closed string duality, and topological gravity.
Exact solutions in supergravity theory
James Liu (Michigan)
I will begin with an introduction to supergravity, focusing on theories in 10 and 11 dimensions, which
are closely connected to string theory. Of particular interest are supergravity configurations preserving
some fraction of supersymmetry. These include typical string backgrounds such as Calabi-Yau spaces
as well as gravitational objects such as supergravity p-branes and BPS black holes. I will discuss the
construction and classification of such BPS solutions, focusing especially on the analysis of the Killing
spinor equations and holonomy in supergravity.

Topic and Speakers (cont.)
The black hole information paradox
Samir Mathur (Ohio State)
We will start by understanding Hawking radiation from black holes, and why this creates a conflict
with quantum mechanics. We will review how string theory leads to an understanding of black hole
entropy. We will then ask: What is the internal structure of a black hole? We will construct the
microstates for 2-charge black holes, and also see how some microstates for 3-charge holes can be
constructed. We will try to extend the lessons learnt here to conjecture how generic black holes
would behave like `fuzzballs' where the entire region inside the `horizon' is nontrivial and carries
the information of the black hole state.
Intersecting branes
Rodolfo Russo (CERN)
D-branes provide a natural framework for realizing in string theory two main building blocks of the
Standard model: non-abelian gauge symmetries and chiral fermions. We start by showing how these
features arise naturally in configurations with intersecting D-branes (or, in the T-dual language, Dbranes with fluxes). Then we discuss tree-level (disk) string amplitudes and show how to derive the
low energy effective action from string computations. Finally we will discuss some possible
phenomenological applications of this string constructions.
Branes and fluxes in string theory and M-theory
Washington Taylor (MIT)
We begin with an overview (no technical details) of the current status of string theory: perturbative
string theories, dualities, D-branes,M-theory and nonperturbative formulations of string theory. Dbranes are then described in more detail from the points of view of 10D supergravity and
perturbative string theory. Fluxes on D-branes are introduced and used to show how D-branes of one
dimension can describe D-branes of another dimension.Finally, fluxes in supergravity are introduced
and used to stabilize moduli of string compactifications.
