Abstract

The aim of this paper is to show that Lawson’s foliation on the $5$-sphere admits a smooth leafwise symplectic structure. The main part of the construction is to show that the Fermat type cubic surface admits an end-periodic symplectic structure. The results is paraphrased that the $5$-sphere admits a regular Poisson structure of symplectic dimension $4$.
