Foliations of Knot Complements in the Bicylinder Boundary
Separata do Boletim da Sociedade Brasileira de Matematica Vol. 5, No. 1 (1974), pp. 31-43.
This paper examines the surfaces and hypersurfaces that arise when considering functions of two complex variables, and by taking implicitly defined loci of the form f(z,w) = 0. This problem has applications in determining the foliations of the sphere, and in determining singularities on algebraic curves.
