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.

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.
