6:15 PM	Libor Snobl (University of Montreal)
		Poisson-Lie T-plurality and 3-dimensional conformally invariant sigma models
		Abstract:
		I shall briefly discuss the notion of Poisson-Lie T-dual, or more precisely 
		Poisson-Lie T-plural models. Then, starting from the classification of 6-dimensional
		Drinfeld doubles and their decomposition into Manin triples I shall construct 
		3-dimensional PLT-plural models. Of special interest are those that are conformally 
		invariant on the 1-loop level, i.e. satisfy vanishing beta function equations. 
		Examples of such models will be presented.

6:30 PM	Diego Chialva (SISSA, Trieste, Italy)
		Long-Living Strings
		Abstract:
		Long-Living non-supersymmetric strings are of interest for many areas of cosmology, 
		first of all for Cosmic Strings. I will identify what are supposed to be the 
		perturbative fundamental string states with the longest life-time, I will describe 
		their dynamics and in particular their gravitational emission. Hints to strings in 
		the KKLMMT model are given.

6:45 PM	Mboyo Esole (Lorentz Institute, Leiden University)
		Geometric engineering of the first cosmic D string action in N=2 supergravity
		Abstract:
		Type IIB superstring compactified on a Calabi-Yau manifold gives an N=2 supergravity 
		theory in four dimensions. Cosmic string solutions in N=2 supergravity could then 
		provide a low energy description of cosmic superstrings. However,there is topological 
		obstruction that prevents the existence of cosmic string potential in N=2 supergravity.
		Therefore cosmic string actions are only known in N=1 supergravity. I explain how to 
		consistently obtain cosmic string actions and solutions in N=2 supergravity using new
		ideas in quaternionic and special Kahler Hodge geometry. The method can be applied to
		other BPS objects and enlarge the family of structures that admit an N=2 supergravity
		description.

7:00 PM	Dieter Van den Bleeken (Institute for Theoretical Physics, Katholieke Universiteit Leuven)
		Dirac actions for D-branes on backgrounds with fluxes
		Abstract:
		I will review the way to get the fermionic part of the action for a d-brane living in
		a general bosonic background. Also I will shortly mention how this leads to a natural
		redefinition of the worldvolume geometry.



Session 5,  Friday  July 1
Chair  Carlos Hoyos 

6:00 PM	Mihai Bondarescu ( California Institute of Technology )  
		Simple solutions to the Einstein Equations in spaces with unusual topology
		Abstract:
		We discuss simple vacuum solutions to the Einstein Equations in five dimensional space-times compactified 
		in two different ways. In such spaces, one black hole phase and more then one black string phase may exist. 
		Several old metrics are adapted to new background topologies to yield new solutions to the Einstein Equations. 
		We then briefly talk about the angular momentum they may carry, the horizon topology and phase transitions 
		that may occur.



Session 6, Monday July 4
Chair  Mihai Bondarescu

6:15 PM	Paul Koerber (University of British Columbia, Vancouver)
		Supersymmetry and generalized complex structures
		Abstract:
		I will discuss conditions for unbroken susy in compactifications with fluxes in the context of generalized complex 
		structures. I'll introduce the notions of generalized complex structure, generalized Kaehler structure and generalized
		Calabi-Yau geometry. The talk is an invitation to hep-th/0506154 which is in fact on D-branes wrapping generalized 
		calibrations in this setup.

6:30 PM	Zoar Komargodski (Weizmann Institute of Science)
		Tachyon condensation in the dynamics of time dependent backgrounds
		Abstract:
		The known results in the simplest time dependent backgrounds will be reviewed. I will explain the physics behind 
		the failure of perturbative string theory to generate finite correlation functions. Then, alternative way of thinking 
		about the dynamics will be proposed and a specific example will be analyzed briefly.

6:45 PM	Dan Gorbonos (Hebrew University)
		A Dialogue of Multipoles: Matched Asymptotic Expansion for Caged Black 
		Abstract:
		No analytic solution is known to date for a black hole in a compact dimension. We develop an analytic perturbation 
		theory where the small parameter is the size of the black hole relative to the size of the compact dimension. We set 
		up a general procedure for an arbitrary order in the perturbation series based on an asymptotic matched expansion 
		between two coordinate patches: the near horizon zone and the asymptotic zone. The procedure is ordinary 
		perturbation expansion in each zone, where additionally some boundary data comes from the other zone, and so 
		the procedure alternates between the zones. It can be viewed as a dialogue of multipoles where the black hole 
		changes its shape (massmultipoles) in response to the field (multipoles) created by its periodic "mirrors", and that 
		in turn changes its field and so on.



Session 7,  Wednesday July 6
Chair  Mihai Bondarescu

6:15 PM	Filippo Passerini (K.U.Leuven)
		Non-relativistic string theory
		Abstract:
		Non-relativistic string theory is a particular sector of string theory. After some motivations, I will show how the non 
		relativistic limit can be taken for foundamental  strings and D-p branes and I will describe some peculiarity of the 
		theory.

6:30 PM	David Vegh (Massachusetts Institute of Technology) 
		Brane tilings
		Abstract:
		It has been a longstanding open problem in string theory to be able to figure out the gauge theory dual to any given 
		string background. Often it is possible to make some headway and find the matter content of the field theory, but it is
		 a difficult problem in general to compute the superpotential. Recent progress in connecting "brane tilings" and 
		dimers has led to a great simplification of this problem.In this talk, I will give a short introduction with examples.

6:45 PM	Niklas Johansson (Uppsala University)
		Boys will NOT be boys - genus mixing and holomorphic factorization in the 0A matrix model
		Abstract:
		The free energy of the 0A matrix model is related to the sum of topological and antitopological string amplitudes. 
		Mixing of different genus terms leads to a sensible geometric interpretation of the matrix model at arbitrary integer 
		multiples of the self-dual radius.

7:00 PM	Carlos Hoyos  (Universidad Autonoma de Madrid, Spain)
		Holographic chiral anomaly
		Abstract:
		The physics of the U(1) axial symmetry can be realized in a supergravity dual of a confining theory with massless 
		flavor and theta angle. Agreement with Witten-Veneziano formula is found.

		Flow of geometries and instantons on the null orbifold
		I have  briefly described the content of the paper  hep-th/ 0507067  whose full entry is  "Flow of geometries and 
		instantons on the null orbifold"  by Micha Berkooz, Zohar Komargodski, Dori Reichmann,  Vasim Shpitalnik
