An 8-dimensional non-formal simply connected symplectic manifold

TL;DR

This paper constructs an 8-dimensional simply connected compact symplectic manifold that is non-formal, contributing to the understanding of symplectic topology and the properties of such manifolds.

Contribution

It provides the first explicit example of a non-formal simply connected symplectic manifold in dimension 8.
