|タイトル||Quotients of étale groupoids and the abelianizations of groupoid C*-algebras|
2019年4月18日 13:00 - 14:00 + 30min.
|場所||Yagami campus, Keio Univ.
Building 14, Room 631A/B
|内容||The study of C*-algebras associated to étale groupoids, known to be
groupoid C*-algebras, was initiated by Renault in 1980.
It is a natural task to characterize the property of groupoid
C*-algebras by the language of étale groupoids.
In this talk, the speaker give an overview of groupoid C*-algebras and
quotient étale groupoids.
Then, the speaker talk about applications of quotients to analysis of the ideal structure and the abelianizations of groupoid C*-algebras. This talk is based on the preprint "Quotients of étale groupoids and the abelianizations of groupoid C*-algebras" (arXiv:1812.07194) by the speaker.
