SUMMARY:K-theory of the integers and the Kummer-Vandiver conjecture
DESCRIPTION:Lorenzo Mantovani: Suspended Tits buildings\nGeorg Tamme: K4(Z) is the trivial group \nTalk 9: Suspended Tits buildings (07.02. Lorenzo Mantovani)\nThis talk covers the results of [Rog00\, §5\, §6]. Explain the explicit identifications of the poset rank filtration and its subquotients for stable apartments [Prop. 5.1\, Prop. 5.4]. Introduce Tits buildings and explain the relation between the Tits buildings of a PID and its fraction field [Lem. 6.1]. Maybe arrange with the subsequent talk’s speaker to cover some material from [§7] in order to alleviate their job.\nTalk 10: K4(Z) is the trivial group (07.02. Georg Tamme)\nThis talks covers the results of [Rog00\, §7\, §8]. Introduce the component filtration of stable\nbuldings [Def. 7.1] and explain (as much as time permits) the associated spectral sequence\nE1 s\,t = Ht(GLk(R); Zs) ⇒ Hs+t( ̄Fk K(R)). Finally\, explain what we can conclude about the rank filtration spectral sequence for K(Z) modulo the Serre subcategory of finite 2-groups [(8.4)]. Compute the low degrees of the spectrum homology H∗(K(Z)) of the spectrum K(Z) [Thm. 8.5] and subsequently the vanishing of K4(Z) [Thm. 8.6].

SUMMARY:Moduli of Langlands parameters
DESCRIPTION:Jean-François Dat (Sorbonne Université\, Paris): Finiteness of Hecke algebras \nTalk 13 (14:00-15:30): Finiteness of Hecke algebras\nThe first goal of the talk is to give an introduction to Fargues-Scholze’s theory of local excursion algebras. Along with previous results covered in the seminar\, these will then be used to deduce finiteness results for Hecke algebras of p-adic groups. \nTalk 14 (16:00-17:00): Second adjointness\nThe goal of this talk is to deduce and explain certain consequences of\nthe finiteness results from the previous talk\, including second\nadjointness. \nZoom: Meeting-ID: 61220727363 \nPassword: largest six digit prime

SUMMARY:Buildings
DESCRIPTION:Timo Richarz (TU Darmstadt): Algebraic loop groups and their flag varieties \nAbstract: Loop groups and their associated flag varieties naturally occur in geometric approaches to the Langlands program. Prominent examples include so-called affine Grassmannians. In this talk I give an introduction to the topic focussing on algebro-geometric aspects and relations with Bruhat-Tits theory.
