DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/119/">T
 aut smoothings and shortest geodesics</a>\nby Macarena Arena (Cambridge) a
 s part of Geometry and topology online\n\nLecture held in Room B3.02 in th
 e Zeeman Building\, University of Warwick.\n\nAbstract\nIn this talk we wi
 ll discuss the connection between combinatorial properties of minimally se
 lf-intersecting curves on a surface \\(S\\) and the geometric behaviour of
  geodesics on \\(S\\) when \\(S\\) is endowed with a riemannian metric. In
  particular\, we will explain the interplay between a smoothing\, which is
  a type of surgery on a curve that resolves a self-intersection\, and k-sy
 stoles\, which are shortest geodesics having at least k self-intersections
 \, and we will present some results that partially elucidate this interpla
 y.\n
