DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/42/">Gr
 aphical small cancellation and groups of type \\(\\mathrm{FP}\\)</a>\nby I
 an Leary (Southampton) as part of Geometry and topology online\n\n\nAbstra
 ct\n<p>\n        Graphical small cancellation was introduced\n        by G
 romov to embed an expanding family inside the Cayley graph\n        of a f
 initely generated group.  We use this technique to\n        construct a la
 rge family of groups of type \\(\\mathrm{FP}\\)\, most of\n        which a
 re not finitely presented.  This is the first time\n        non-finitely p
 resented groups of type \\(\\mathrm{FP}\\) have been\n        constructed 
 <i>without</i> using Bestvina-Brady Morse theory.\n        I will give an 
 idea of how graphical small cancellation works\n        and how we use it.
