Permanence properties of the second nilpotent product of groups
(Belgian Mathematical Soc Triomphe, 2019-07)
We show that amenability, the Haagerup property, the Kazhdan´s property (T) and exactness are preserved under taking second nilpotent product of groups. We also define the restricted second nilpotent wreath product of ...
