DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FOTR/63/">Ne
 w instances of equivariant Noetherianity</a>\nby Jan Draisma (Universität
  Bern) as part of Fellowship of the Ring\n\n\nAbstract\nWhen a group or mo
 noid G acts on a ring R by means of endomorphisms\, we say that R is G-Noe
 therian if every ascending chain of G-stable ideals in R is eventually con
 stant\; and we call R *topologically* G-Noetherian if this condition holds
  at least for chains of G-stable radical ideals.\n\nOver the last 15 years
 \, many examples of (topologically) G-Noetherian rings have been discovere
 d. I will first discuss some of the older results and their motivation. He
 re G is usually the infinite symmetric group Sym or the infinite general l
 inear group GL over an infinite field.\n\nAfter that\, I will turn to rece
 nt joint work with Chiu-Danelon-Eggermont-Farooq on examples where G=Sym x
  GL\; and with Blatter-Rupniewski on examples where G=GL over a finite fie
 ld.\n
