The article deals with symplectic harmonic forms. A recent result by O. Mathieu states: For a symplectic manifold of \(\dim 2n\) the following properties are equivalent: (1) There exists a harmonic cocycle in every cohomology class and (2) the cup product is surjective. This article provides an alternative, more direct proof for this fact using a particular \(\text{sl}(2,C)\) representation. An application in symplectic differential topology concludes the paper.
