Set-Theoretic Topology and Topological Algebra

Professor Alexander Vladimirovich Arhangelskii more than forty-five years works at the Faculty of Mechanics and Mathematics, of which over thirty years in the position of professor. A.V. Arhangelskii is a pupil of Academician P.S. Alexandroff, who, together with P.S. Uryson founded the Russian (Soviet) topological school. And to this day the Russian topological school is one of the best in the world. His scientific results became classical and laid the foundation for such scientific areas as topological algebra, spaces of continuous functions, topological homogeneity. He wrote more than 330 works, more than fifty times A.V. Arhangelskii was an invited speaker at international conferences and symposiums. Monographs of A.V. Arhangel’skii “Topological function spaces”, “Cantor set theory”, “Finite-dimensional vector spaces”, “Topological groups and related structures” (joint with M.G. Tkachenko) and joint with V.I. Ponomarev textbook “Fundamentals of General Topology in Problems and Exercises” became reference books for many mathematicians and translated into foreign languages. He established in Russia an authoritative scientific school: among the students of A.V. Arhangelskii 37 candidates and doctors of science, among them more than 20 professors.

Topics include:
  1. Set-Theoretic Topology
  2. Mappings and Spaces
  3. Topological groups
  4. Topological function spaces

Dilip Raghavan : “Boolean ultrapowers and iterated forcing”


In joint work with Saharon Shelah, we develop a new method for proving consistency results on cardinal invariants, particularly results involving the invariant . This method can be used with a wide range of forcing notions, including arbitrary ccc posets. However the method always requires a supercompact cardinal κ in the ground model and produces forcing extensions in which the desired invariants sit above κ. Another feature of our method is that it generalizes to cardinal invariants above ω, and can be used to give uniform consistency proofs that work at any regular cardinal. It can also be used to treat situations where three cardinal invariants must be separated. In particular, our technique solves various long standing open problems about cardinal invariants at uncountable regular cardinals. All the results use Boolean ultrapowers, studied by Keisler and other model theorists in the 1960s. I will aim to give a fairly self contained introduction to this method and to some to its applications to the theory of cardinal invariants.

Generalised Baire Spaces, Amsterdam, August 22-24, 2018

KNAW Academy Colloquium

Generalised Baire Spaces

Amsterdam, The Netherlands

Master Class: 22 August 2018 / Colloquium: 23–24 August 2018

Organisers. Lorenzo Galeotti, Benedikt Löwe, Philipp Lücke.
Descriptive set theory and set theory of the reals traditional deal with well-known and well-studied topological spaces such as the real numbers, Cantor space, and Baire space. In recent years, set theorists are increasingly interested in the uncountable analogues 2κ of the Cantor space (generalised Cantor space) and κκ of the Baire space (generalised Baire space) for uncountable cardinals κ.

While many concepts from the classical setting can be transferred to generalised Baire space and some classical results remain true at uncountable cardinals, in general the rich combinatorial nature of uncountable cardinals causes the theory of the corresponding spaces to differ significantly e.g., notions which are equivalent in the classical setting can lead to different notions in the generalised theory. Phenomena like this shed light on structures and properties otherwise hidden in the classical setting.

The study of generalised Baire spaces has developed into a research area in its own right with a rich overarching theory, internally motivated open questions (cf. Khomskii, Laguzzi, Löwe, Sharankou 2016) and an active research community, combining methods and techniques from several branches of set theory like uncountable combinatorics, forcing, large cardinals, inner models and classical descriptive set theory and also involves techniques from classical model theory. The community met first at the Amsterdam Set Theory Workshop 2014 in November 2014, then at a satellite workshop to the German mathematics congress in Hamburg in September 2015, and finally at a workshop at the Hausdorff Center for Mathematics in Bonn in September 2016. This Academy Colloquium is a reunion of the community after a hiatus of two years.

The Colloquium will be preceded by an associated KNAW Master Class for postgraduate students in order to prepare them for the talks at the Colloquium. The KNAW Master Class will take place on 22 August 2018.
