DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/31/">
 Amphichiral knots with large 4-genera</a>\nby Allison Miller (Rice Univers
 ity) as part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\n\
 nAbstract\nAn oriented knot is called negative amphichiral if it is isotop
 ic to the reverse of its mirror image. Such knots have order at most two i
 n the concordance group\, and many modern concordance invariants vanish on
  them. Nevertheless\, we will see that there are negative amphichiral knot
 s with arbitrarily large 4-genera\, using Casson-Gordon signature invarian
 ts as a primary tool.\n
