• Thistlethwaite theorems for knotoids and linkoids2025 · аннотациясвернуть

  An extension of the classical Thistlethwaite theorem for links asserts that the Kauffman bracket of a link can be obtained from an evaluation of the Bollobás–Riordan polynomial of a ribbon graph associated to one of the…

• Generalized chord diagrams and weight systems2025
• Chromatic polynomial and the $\mathfrak{so}$ weight system2025
• Polynomial graph invariants induced from the gl -weight system2025
• К 80-летию Юлия Сергеевича Ильяшенко2025
• An algebro-geometric proof of Witten’s conjecture2007 · аннотациясвернуть

  We present a new proof of Witten’s conjecture. The proof is based on the analysis of the relationship between intersection indices on moduli spaces of complex curves and Hurwitz numbers enumerating ramified coverings of…

• Mutant knots and intersection graphs2007 · аннотациясвернуть

  We prove that if a finite order knot invariant does not distinguish mutant knots, then the corresponding weight system depends on the intersection graph of a chord diagram rather than on the diagram itself. Conversely,…
