DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Knotsandtopo

 r M. Nikonov as part of Knots and representation theory\n\nInteractive liv

 sV2pnQT09\n\nAbstract\nWe consider graph-links --- combinatorial objects i
 ntroduced by D.P. Ilyutko and V.O. Manturov. A graph-link is defined as an
  equivalence class of simple labeled graphs with respect to special transf
 ormations which play the role of Reidemeister moves. This theory naturally
  describes classical and virtual links up to mutation.\n \nThe aim of the 
 talk is to introduce orientation on graph-links. Further\, we define some 
 invariants of oriented graph-links and\, based on these invariants\, carry
  out a classification of oriented graph-links of low complexity (with at m
 ost $4$ vertices).\n
