The initial idealistic perspective associated with the concept of globalization has turned into a bleak evidence in the present, which has taken on the appearance of a disharmonious liberalism in which it is possible to observe a common worldwide inc

We prove that the space of traces $\text{T}(A)$ of the unital full free product $A=A_1*A_2$ of two unital, separable $C^*$-algebras $A_1$ and $A_2$ is typically a Poulsen simplex, i.e., a simplex whose extreme points are dense. We deduce that $\text{

For a class of wreath-like product groups with property (T), we describe explicitly all the embeddings between their von Neumann algebras. This allows us to provide a continuum of ICC groups with property (T) whose von Neumann algebras are pairwise n

We prove novel asymptotic freeness results in tracial ultraproduct von Neumann algebras. In particular, we show that whenever $M = M_1 \ast M_2$ is a tracial free product von Neumann algebra and $u_1 \in \mathscr U(M_1)$, $u_2 \in \mathscr U(M_2)$ ar

We prove that if $A$ is a non-separable abelian tracial von Neuman algebra then its free powers $A^{*n}, 2\leq n \leq \infty$, are mutually non-isomorphic and with trivial fundamental group, $\mathcal F(A^{*n})=1$, whenever $2\leq n<\infty$. This set

We prove that if a separable II$_1$ factor $M$ is existentially closed, then every $M$-bimodule is weakly contained in the trivial $M$-bimodule, $\text{L}^2(M)$, and, equivalently, every normal completely positive map on $M$ is a pointwise 2-norm lim

The spatial organization of enterprises is of great importance for the metallic materials industry (metallurgy), given the diversity and complexity of the technological processes and the related equipment. In an enterprise from the metallic materials

We introduce a new iterative amalgamated free product construction of II$_1$ factors, and use it to construct a separable II$_1$ factor which does not have property Gamma and is not elementarily equivalent to the free group factor $\text{L}(\mathbb F

In the first part of the paper we survey several results from Popa's deformation/rigidity theory on the classification of tensor product decompositions of large natural classes of II$_1$ factors. Using a m\'elange of techniques from deformation/rigid
