Abstract:Jacobian elliptic surfaces are elliptic surfaces with sections. They play a
key role in gauge theory as well as in string theory. In gauge theory, the Seiberg-
Witten curve of SU(2) gauge theory arises as a pencil generated by two cubics in
the plane forming a rational elliptic surface. In F-theory, K3 surfaces constructed as
elliptic surfaces with sections are also of special importance.
In my talk, I will start with the Weierstrass normal form of the Seiberg-Witten
curve for pure SU(2) gauge theory. By carrying out a base transformation, one obtains
a 3-parameter family of elliptically fibered K3 surfaces. The gauge theoretic relation
between the Seiberg-Witten curves with Nf = 2 and Nf = 0 hypermultiplets in
turn defines a Shioda-Inose structure on each K3 surface in the family with quotient
birational to a Kummer surface of the Jacobian of a genus-two curve.
