PhDs in Logic, Prague, May 2018

Dear all,

The set theory section of the PhDs in Logic meeting is scheduled for the
morning of Wednesday May 2nd. The seminar next Wednesday is cancelled.
The PhDs in Logic meeting meeting takes place in the Institute of
Philosophy CAS, Jilska 1, Prague 1. The programme is available here:


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.
