DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITTop/29/">
 Unstable modules with only the top k Steenrod operations</a>\nby Zhulin Li
  (MIT) as part of MIT topology seminar\n\n\nAbstract\nIn this talk\, I wil
 l introduce unstable modules with only the top k Steenrod operations at th
 e prime 2. I'll show that they have projective dimension at most k. Then I
 'll establish forgetful functors\, suspension functors\, loop functors and
  Frobenius functors between such modules. The forgetful functors induce an
  inverse system of Ext groups\, and the inverse system stabilizes when the
  covariant module is bounded above. In addition\, I will talk about a gene
 ralization of the Lambda algebra which computes the Ext group from such mo
 dules to suspensions of the base field.\n
