Colloquium [April 23, 2015]

2015.04.15 Wed up
April 23, 2015 @BKC campus, Forest House F109, 16：30–18:00

1. Time: 16:30 — 17:10
Seung-Hyeok Kye;（Seoul National University）
Title  :Positive bi-linear maps as tri-partite entanglement witnesses
abstract:
We introduce various notions of positivity for bi-linear maps in operator systems. They are witnesses for various notions of tri-partite entanglement when the domains and ranges are matrix algebras. We present concrete examples of witnesses for three qubit entanglement.

2. Time: 17:20 — 18:00
Kazuki Utsumi （Ritsumeikan University）
Title  : Classification problems of Jacobian fibrations on K3 surfaces
abstract : 
Jacobian fibrations on K3 surfaces can be regarded as elliptic curves over the rational function field. We introduce classification problems and their answers for some K3 surfaces.
