Abstract
We prove that basket links, whose symmetrized Seifert form is congruent to the Cartan matrix of the simply laced Dynkin diagram , are isotopic to the torus link . In addition, we provide examples of links, constructed by plumbing positive Hopf bands the core curves of which intersect at most once, with symmetrized Seifert form congruent to the Cartan matrix , that are not isotopic to .
