DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCDANT/6/">T
 ame derivatives and the Eisenstein ideal</a>\nby Preston Wake (Michigan St
 ate) as part of Dublin Algebra and Number Theory Seminar\n\n\nAbstract\nAs
  was made famous by Mazur\, the mod-5 Galois representation associated to 
 the elliptic curve $X_0(11)$ is reducible. Less famously\, but also noted 
 by Mazur\, the mod-25 Galois representation is reducible. We'll explain wh
 y this mod-5 reducibility is to be expected\, but why this mod-25 reducibi
 lity is surprising. We'll also discuss the analytic and algebraic signific
 ance of the characters that appear in the mod-25 representation.\n
