Abstract
We extend a result of M. Katz on conformal systoles to all four-manifolds with \(b_2^+=1\) which have odd intersection form. The same result holds for all four-manifolds with \(b_2^+=1\) with even intersection form and which are symplectic or satisfy the so-called \(\frac{5}{4}\)-conjecture.
