## Valentina Giangreco (26/05/17)

Math Colloquium

### Speaker: Valentina Giangreco, University of Iceland

### Title: Non-analyticity of holographic Rényi entropy in Lovelock gravity

Location: Tg-227 (Tæknigarður, 2. hæð)

Time: Friday 26 May at 13:20

### Abstract:

In the first part of my talk I will introduce the definition of Rényi entropy, and some basic concepts of the so-called holographic principle (AdS/CFT). The second part of the talk is devoted to the analysis of certain black hole instabilities in gravity theories with higher derivative corrections (Lovelock gravity theories) and their implications for the holographic Rényi entropy.
