DESCRIPTION:Title: Boundary-corner contributions to entanglement entropy.\n
 \nAbstract: The entanglement entropy\, while being under the spotlight of 
 theoretical physics for quite some time now\, remains a very challenging q
 uantity to compute\, even in free quantum field theories\, and a number of
  issues are yet to be fully explored. One such issues concerns boundary ef
 fects on entanglement entropy\, which is important both for theoretical ex
 plorations of entanglement and for applications of entanglement entropy to
  lattice simulations\, condensed matter systems\, etc.. During this talk\,
  I will show how the presence of spacetime boundaries affects the entangle
 ment entropy. To that end\, I will introduce different methods: field theo
 retic\, lattice\, and holographic. Focus will be on entangling surfaces th
 at intersect the space boundary\, and special attention will be given to t
 he universal logarithmic contributions that such configurations produce in
  the entanglement entropy.\n
