    • A Divisibility theorem for the Alexander polynomial of a plane algebraic curve 

      Degtyarev, A. I. (Springer New York LLC, 2004)
      An upper estimate for the Alexander polynomial of an algebraic curve is obtained, which sharpens Libgober's estimate in terms of the local polynomials at the singular points of the curve: only those singular points may ...
    • Oka's conjecture on irreducible plane sextics II 

      Degtyarev, A. (2009)
      We complete the proof of Oka's conjecture on the Alexander polynomial of an irreducible plane sextic. We also calculate the fundamental groups of irreducible sextics with a singular point adjacent to J10. © 2009 World ...
