/**
**Title: Torsion Subgroups of Hyperelliptic Jacobian Varieties**

**
**Abstract: **In this talk, we explore some number theoretic aspects of 
hyperelliptic curves. It is known that the number of isomorphism classes 
of hyperelliptic curves with the same discriminant over a fixed number 
field is finite. A more challenging task is to count, if not list, all 
such isomorphism classes. We also present explicit constructions of 
hyperelliptic Jacobian varieties with rational torsion points of 
prescribed order.
