Ayodeji Lindblad

Welcome to my website.

My CV can be found at this link and the research papers I’ve written are listed below:

• Designs related through projective and Hopf maps [In Discrete & Computational Geometry]
  Formalizes a construction that builds a spherical t-design by placing a spherical t-design on each projective or Hopf fiber associated to the points of a ⌊t/2⌋-design on a quotient projective space or sphere Σ. This generalizes work of König, Kuperberg, and Okuda, who verified the cases when Σ is a complex projective space or S2.

• Asymptotically optimal t-design curves on S3 [arXiv:2408.04044, submitted for publication]
  Solves the dimension 3 case of the problem posed by Ehler and Gröchenig of proving that there exist asymptotically optimal sequences of t-design curves on Sd for d > 2.

• Asymptotically short generalizations of t-design curves [arXiv:2505.03056, to be submitted for publication]
  Proves existence of weighted and εt-approximate t-design curves on Sd of asymptotic order of arc length td-1 for all d in the weighted setting (in which case such curves are asymptotically optimal) and for all odd d in the approximate setting (in which case εt ≍ 1/t as t → ∞). Explicit formulas for such weighted t-design curves are given for d ∈ {2, 3}. 

• Dynamical stability of translators under mean curvature flow [Available on SPUR website]
  Joint w/ Carlos Alvarado, produced under the supervision of Tang-Kai Lee as part of MIT SPUR 2022. Investigates whether certain classes of perturbations of mean curvature flow translators converge to translators under the flow. 

• Abelianized boundary Dehn twists on connected sums of complete intersections [Writeup in progress, to be released 1/13/2026].

• Lifting design curves [Writeup in progress, to be released 3/3/2026].

Some expository works I’ve written can also be found below:

• Instanton Floer homology and applications [To appear].
  Notes following a mini-course given by Tom Mrowka and John Baldwin written joint w/ Joye Chen, Ollie Thakar, and Nathan Geist. In specific, I wrote the sections following Tom’s lectures joint w/ Tom and Joye and made figures for both the sections following Tom’s lectures and those following John’s lectures.

The following are talks I’ve given:

• Geometrically designing geometric designs [3/14/2025 @ MIT PuMaGraSS]
  I discussed geometric constructions of spherical t-designs and t-design curves.

• Monopole Floer homology and a refinement of Manolescu [10/15/2024 @ MIT Juvitop]
  I gave an overview of the construction of monopole Floer homology (as in Ch. 22 of Tom and Peter’s book) and discussed a refinement due to Manolescu involving finite-dimensional approximations of the Seiberg-Witten map which produces a space whose homotopy groups are the monopole Floer homology groups.

• In case you’re curious what your local low-dimensional topologists do all day [10/4/2024 @ MIT PuMaGraSS]
  I spoke about Morse theory and Floer theories.

• Designs related through projective and Hopf maps [4/6/2024 @ 2024 AMS Eastern Sectional meeting FRACTals section]
  I discussed my preprint of the same name.

The following are meetings I’ve organized:

• The Low-dimensional Princeton-Cambridge Exchange Gathering (the Low PriCE Gathering) [4/2-4/4/2025 @ MIT and Harvard]
  A meeting on low-dimensional topology which I organized alongside Ollie Thakar. Abstracts from the event can be found here.

If you see someone who looks like this around the MIT math department, they’re probably me.
