Overview

Starting from my PhD thesis Towards a Bezout-type Theory of Affine Varieties written at University of Toronto under the supervision of Pierre Milman, my research in math falls under two broad themes:

• Compactification of affine varieties
• Affine Bézout problem

I am in particular interested in one of the simplest cases of the first problem:

• Compactification of \(\mathbb{C}^2\)

Papers

  Note: I had signed the pledge to boycott Elsevier. I came to know of the submission of this article to the Journal of Algebra only after the fact (Tim made this submission, and he was not aware of my pledge). I was too shy to ask him to withdraw the submission – this I regret now.
