DESCRIPTION: Speaker: Raimon Luna (CENTRA)Title: &quot\;The large D limit 
 of General Relativity&quot\;Abstract:In this seminar I will give an overvi
 ew of the recent developments in the Large D limit of gravity. In this app
 roach\, we explore the limit General Relativity as the number of dimension
 s grows very large\, which allows us to perform perturbative analysis with
  asymptotic expansions in powers of 1/D\, with D being the dimension of sp
 acetime. This makes it possible to access analytically (or with very modes
 t numerical techniques) the physics of black holes\, both in D=4 and in hi
 gher dimensions. In particular\, I will focus on the effective theory for 
 black holes with extended directions (mainly black strings and black brane
 s) which has been used to recover the critical dimension of black strings\
 , and most importantly to predict violations of Penrose&#x27\;s Weak Cosmi
 c Censorship conjecture in black hole mergers through the so-called blobol
 ogy formalism.For those who cannot attend the seminar in person\, we will 
 also broadcast it through zoom: https://videoconf-colibri.zoom.us/j/850370
