Alexander polynomials of non-locally-flat knots
Alexander polynomials of non-locally-flat knots
We generalize the classical study of Alexander polynomials of smooth or PL locally-flat knots to PL knots that are not necessarily locally-flat.We introduce three families of generalized Alexander polynomials and study their properties.For knots with point singularities, we obtain a classification of these polynomials that is complete except for one …
