The Ministry of Science and Higher Education has approved funding for the "Virgo-PL: Polish Participation in the Virgo Gravitational Wave Observatory" project under the "Support for Polish Research Teams' Participation in International Research Infrastructure Projects" programme.
The applicant - Polish Consortium of the Virgo Project- comprises several institutions: the Mathematical Institute of the Polish Academy of Sciences (IMPAN), the Nicolaus Copernicus Astronomical Centre of the Polish Academy of Sciences (CAMK PAN), the Academic Computer Centre Cyfronet, AGH University of Science and Technology, the National Centre for Nuclear Research (NCBJ), the University of Białystok (UwB), Jagiellonian University (UJ), and the University of Warsaw (UW).
The project aims to engage the Polish Consortium institutions in using and developing the Virgo gravitational wave detector. This detector is part of a global network that includes similar observatories in Europe (Virgo), the USA (LIGO), and Japan (KAGRA). The project consists of seven tasks outlined in an agreement between the Polish Consortium and the European Gravitational Observatory (EGO). These tasks include financial contributions to EGO, enhancing the sensitivity of the Virgo detector, characterizing noise in the detector, contributing to the computational network of the International Gravitational-Wave Observatory Network (IGWN), analyzing data from the global gravitational wave detector network, and promoting the results of the Virgo project.
The Mathematical Institute of the Polish Academy of Sciences serves as the project leader, with Prof. Andrzej Królak as the coordinator. IMPAN's responsibilities include providing financial contributions to EGO, analyzing data from Virgo, KAGRA, LIGO, and other detectors, and coordinating the project.

Title: Introduction to the classification of simple nuclear C*-algebras
Abstract: In this talk, I'll give an introduction to simple nuclear C*-algebras and their classification. This will be illustrated by examples coming from group actions. My aim will be to describe at a high level the paradigm shift from using internal structure to classify, to obtaining internal structure from classification that Chris Schafhauser's work made possible. No prior knowledge of operator algebras will be assumed.

Title: Lifting problems in C*-algebras and applications
Abstract: A classical problem of Halmos asks which essentially normal operators (those commuting with their adjoint modulo a compact operator) on Hilbert space are compact perturbations of normal operators (those commuting with their adjoint). A complete solution was obtained by Brown, Douglas, and Fillmore in the early 70s, and their solution led to the introduction of algebraic topological methods in operator algebras. In particular, for a compact metric space X, they considered all embeddings of C(X) into the quotient B(H)/K(H) of bounded operators on a Hilbert space modulo the compact operators and showed that homotopy classes of such embeddings form an abelian group K_1(X), which is the degree one term for a generalized homology theory dual to topological K-theory. Building on this, Kasparov developed a much more general extension theory, studying lifting problems along more general quotient maps up to a stabilized notion of homotopy. I will discuss some recent progress in `non-stable’ extension theory with applications to embedding problems and classification problems for simple nuclear C*-algebras.
