Permanence properties of verbal products and verbal wreath products of groups
Javier Brude, Román Sasyk
By means of analyzing the notion of verbal products of groups, we show that soficity, hyperlinearity, amenability, the Haagerup property, the Kazhdan's property (T) and exactness a…
A note on the classification of Gamma factors
Román Sasyk
One of the earliest invariants introduced in the study of finite von Neumann algebras is the property Gamma of Murray and von Neumann. In this note we prove that it is not possible…
The inverse sieve problem for algebraic varieties over global fields
Juan Manuel Menconi, Marcelo Paredes, Román Sasyk
Let be a global field and let be a geometrically irreducible algebraic variety defined over . We show that if a big set of rational points of bounded heig…
An ultrapower construction of the multiplier algebra of a -algebra and an application to boundary amenability of groups
Facundo Poggi, Roman Sasyk
Using ultrapowers of -algebras we provide a new construction of the multiplier algebra of a -algebra. This extends the work of Avsec and Goldbring [Houston J. M…
