Jack Smith

I am a College Associate Lecturer at St John's College, Cambridge, where I am also Director of Studies in Pure Mathematics.

Previously I was a visiting researcher at the Fields Institute, Toronto, a postdoc at University College London, and a PhD student of Ivan Smith.

Here you can find my thesis, me on arXiv, and my department profile page.

I can be contacted by email at j.smith AT dpmms.cam.ac.uk.

Research

My main interests are in mirror symmetry and in interactions between algebra and Floer theory.

  Joint with Matthew Habermann
  arXiv, to appear in J. Symplectic Geom.
• Monotone Lagrangians in \(\mathbb{CP}^n\) of minimal Maslov number \(n+1\)
  Joint with Momchil Konstantinov
  arXiv, to appear in Math. Proc. Cambridge Philos. Soc.

Teaching

In June 2018 I gave a short lecture course on K-theory to PhD students at the London School of Geometry and Number Theory. Expanded notes are availble here.
