L_oo algebra connections and application to String- and Chern-Simons n-Transport
Urs Schreiber
(Hamburg)
Abstract:
We conceive higher bundles with connections entirely Lie algebraically by, essentially, extending the Cartan-Ehresmann definition of a connection from Lie algebras to L-infinity algebras. Using this machinery, we study Chern-Simons n-bundles as obstructions to lifts through String-like extensions of L-infinity algebras.

Reflection Equation and deformation quantization
Andrey Mudrov
(Leicester University)
Abstract:
Reflection equation or boundary Yang-Baxter equation is an important object in the theory
of quantum groups and integrable models, along with the famous RTT relation. In my talk I focus on the role of the related algebraic structures in the deformation quantization. We provide a survey of their basic
properties from a geometric point of view.

Large Extremal Black Holes in AdS5
Sangmin Lee
(Seoul National University)
Abstract:
We study the near horizon geometry of extremal black holes in five dimensional gauged supergravity using Sen's entropy function formalism. Special attention is paid to the large black hole limit where the near horizon solution exhibits a universal dependence on the rotation. The physical properties of the large black hole solution are shown to agree with predictions from fluid mechanical description of the dual conformal field theory.
