Abstract:

Let ${\mathcal {F}_n}$ be a Hirzebruch surface, $n \geqslant 1$. Using the family of extremal metrics on these surfaces constructed by Calabi [1], we study a closely related scale-invariant variational problem, and show that only ${\mathcal {F}_1}$ admits an extremal Kähler metric which is critical for this new functional. Applying a result of Derdzinski [3], we prove that this metric cannot be conformally equivalent to an Einstein metric on ${\mathcal {F}_1}$. When $n = 2$, we show there is a critical orbifold metric on the space obtained from ${\mathcal {F}_2}$ by blowing down the negative section.
