Lectures
CORNALBA, The BFKL Pomeron in AdS/CFT
Abstract: We describe the deep connection between the BFKL pomeron trajectories in N=4 SYM and the corresponding Regge
trajectory of the graviton in AdS. We will discuss both the formal aspects, related to the invariance of highenergy
interactions under the transverse conformal group, as well as more applied aspects,
regarding the physics of deep inelastic scattering at small values of Bjorken x.
FERRARI, On Localization and Some of Its Applications in Supersymmetric Gauge Theories
Abstract: I will introduce the idea of localization and explain its use in recent developments in supersymmetric gauge theories.
I will emphasize in particular the applications to N=1 gauge theories.
GOPAKUMAR, Galilean Conformal Algebras and AdS/CFT
Abstract: We will describe a novel nonrelativistic limit that can be studied within the usual AdS/CFT context. This limit arises from taking a group
contraction of the relativistic conformal symmetry. One of the interesting features of this limit is that the resulting galilean conformal symmetry has an
infinite dimensional extension (in any spacetime dimension). In fact, it contains a VirasoroKacMoody algebra. We also describe the bulk dual
to this nonrelativistic sector in terms of a NewtonCartan like geometric description in which the dynamical variables are not the metric but
rather affine connections. The bulk dual always contains an AdS_{2} whose asymptotic isometries exactly match the infinite
dimensional symmetries found in the boundary description.
HARMARK, New Approaches to HigherDimensional Black Holes
Abstract: We have learned in recent years that black holes in more than four spacetime dimensions is an unexpectedly rich subject.
Starting with the discovery of the black ring in five dimensions it has become clear that many new type of black holes can exist in higher dimensions,
contrary to the fourdimensional case where only one type of black hole exists. For fivedimensional black holes some very powerful techniques
inherited from four dimensions makes it possible to understand the space of black hole solutions, at least assuming certain symmetries.
For more than five dimensions new techniques are needed. I will present in this talk two new approaches to higherdimensional black holes that can help in understanding
the space of black hole solutions, in particular in more than five dimensions. One approach is the blackfold construction of new black holes which essentially
is a worldvolume effective theory of black holes with two highly separate scales. This can be used to construct new types of black hole solutions in
certain regimes with highly separate scales. The other approach is the domain structure which is a classification scheme for black holes.
MARIÑO, Nonperturbative Aspects of the Topological String: A Conservative Point of View
Abstract: In this talk I will review some recent progress in understanding
nonperturbative aspects of matrix models and topological strings from a conservative point of view,
i.e. by relying on old ideas about instanton corrections in quantum theories and their relation to the perturbative
series.
MARTELLI, The AdS/CFT Correspondence and SasakiEinstein Geometry
Abstract: I will review some aspects of the AdS/CFT correspondence, emphasising the
important role played by SasakiEinstein and related geometry. I will discuss classes of supersymmetric quiver gauge theories and their gravity
duals. Examples will include 3D ChernSimons quiver gauge theories in the context of the
AdS_{4}/CFT_{3} correspondence, relevant for understanding
M2branes.
MINWALLA, Thermal Equilibration and Fluid Dynamics from Gravity
Abstract: The AdS/CFT correspondence asserts that every evolution of a strongly coupled large N
conformal field theory admits a dual description as a solution of Einstein's equations coupled to other fields. In particular
the dynamical process of thermalization of conformal field theories is dual to the bulk process of horizon formation, while nearly
equilibrated field theory dynamics  i.e. fluid dynamics  is dual to spacetimes with slowly fluctuating horizons. In this
talk we determine a large class of the relevant gravity solutions by a direct analysis of
Einstein's equations, and learn several lessons about boundary thermalization and fluid dynamics from this process.
RASTELLI, Holography in the Veneziano Limit
Abstract: I will describe recent progress towards the longstanding goal of finding the string theory dual of
N=2 super YangMills with N_{f} = 2
N_{c} fundamental flavors.
SCHOMERUS, Superspace Sigma Models
Abstract: Sigma models on target superspaces are a subject of considerable importance, with a wide range of applications
in statistical physics, condensed matter and string theory. Those will be reviewed in the first part of the first
lecture. The second part is then devoted to supergeometry. In particular, I shall introduce supergroups and cosets,
study their vector fields and determine the spectrum of Laplacians with special emphasis on those features that
are characteristic for supermanifolds. The second lecture discusses basic results and recent developments
in the field of superspace sigma models. Special attention will be payed to models with PSL(NN) symmetry.
Special Events
There will be a welcome reception on Monday evening, after the end of the first conference
day, and on Tuesday night we plan to have the Conference Dinner (please note that,
because there is no registration fee, the dinner will have to be paid by
each participant).
The reception will take place on Monday, at 6pm, in the gardens adjacent to the Department
of Mathematics. Port wine will be served!
The conference dinner will take place on Tuesday, at 8pm (price is 36 euros per person, with
drinks included). The venue: Casa do Alentejo, Rua Porta de Santo
Antão, 58, in the heart of
town. Reachable by subway from the "Alameda" subway stop (get off at
"Rossio" subway station and walk a few meters).
