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.

Research

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

Published and submitted papers:

• Superfiltered \(A_\infty\)-deformations of the exterior algebra, and local mirror symmetry
  arXiv:1910.01096, submitted.
• A monotone Lagrangian casebook
  arXiv:1905.04005, submitted.
• Homological Berglund–Hübsch mirror symmetry for curve singularities
  Joint with Matthew Habermann
  arXiv:1903.01351, submitted.
• Monotone Lagrangians in \(\mathbb{CP}^n\) of minimal Maslov number \(n+1\)
  Joint with Momchil Konstantinov
  arXiv:1810.00833, to appear in Math. Proc. Cambridge Philos. Soc.
• Quantum cohomology and closed-string mirror symmetry for toric varieties
  arXiv:1802.00424, to appear in Q. J. Math. The journal version, which clarifies and updates aspects of the arXiv version, is here.
• Discrete and continuous symmetries in monotone Floer theory
  arXiv:1703.05343, submitted.
• Floer cohomology of Platonic Lagrangians
  J. Symplectic Geom. 17 (2019), no. 2, 477-601
  arXiv:1510.08031 (including Mathematica notebook).

Unsubmitted preprints:

• Generating the Fukaya categories of compact toric varieties
  arXiv:1804.06386, superseded by arXiv:1910.01096 and work in progress.

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.
