Selected Publications

My primary research has been in Topology, Real Analysis, and Measure Theory, and involves classifying sets in topology and analysis (part of an area known as Descriptive Set Theory). I have also been interested in Randomness in Sequences and Non-standard Analysis.

Expository Articles

Topology Atlas was founded by Dmitri Shakhmatov and Stephen Watson in 1995 as a comprehensive online resource for topology, and ran until 2020. It went offline in 2020, but an archive seems to be available again (as of 2024 March) at the original site hosted by York University (partial content also in wayback archives).

The following appeared in Topology Atlas in 2005, under Topology Explained, notes written by Henno Brandsma (Amsterdam) and Abhijit Dasgupta (Detroit), for the Ask a Topologist forum.

  • Countable metric spaces without isolated points, in ``Topology Explained,'' June 2005. (Originally published by Topology Atlas here, local PDF copy here).

  • Limit points of discrete sets in metric spaces, in ``Topology Explained,'' July 2005. (Originally published by Topology Atlas here, local PDF copy here).
