*Title:* Geometric realisation of hypergeometric local systems

*Abstract:*
A hypergeometric local system on P \ { 0,1,\infty}, irreducible and 
defined over $\mathbb{Q}$, is known to be motivic, but which geometry it 
comes from is a separate question.
I will describe an explicit family of affine varieties in an algebraic 
torus and explain that the local system is the top graded piece of the 
weight filtration on the primitive middle compactly supported cohomology 
of the family.
The result is unconditional for families of curves and of 
even-dimensional varieties.


All are welcome to join.
