DESCRIPTION:Speakers: Abhijit Gadde (TIFR\, Mumbai)\n\nIn this talk\, I'll
  describe an intimate connection between multi-partite entanglement and to
 pological field theories. The ground state of a gapped Hamiltonian is expe
 cted to describe a topological quantum field theory at  long distances. A
  natural question is how to describe this TQFT from the properties of the 
 ground state. I'll describe a class of q-partite entanglement observables\
 , called multi-invariants\, that is in one to one correspondence with q-1 
 manifolds M and its bicolored triangulation. We conjecture that these mult
 i-invariants encode the TQFT partition function on M along with non-univer
 sal local factors. We identify the non-universal contributions with less-t
 han-full-partite entangled states and describe a  way of removing them. A
  beautiful connection with null bordisms emerges  in this process.\n\nhtt
