Abstract
We describe a method to construct hypersurfaces of the complex affine -space with isomorphic -cylinders. Among these hypersurfaces, we find new explicit counterexamples to the Laurent Cancellation Problem, i.e. hypersurfaces that are non isomorphic, although their -cylinders are isomorphic as abstract algebraic varieties. We also provide examples of non isomorphic varieties and with isomorphic cartesian squares and .
