Aaron Mazel-Gee

Hello there! My name is Aaron. I like to do math. It is my job.

I am a Sherman Fairchild Instructor in Mathematics at Caltech. My office is 374 Linde Hall.

My research centers around factorization homology, especially as it relates to (i) quantum invariants in low-dimensional topology, and (ii) algebraic K-theory, elliptic cohomology, and chromatic homotopy theory.

My work is partially supported by NSF grant DMS-2105031 (Factorization homology and low-dimensional topology).

My email address is etale.site@aaron, except that you need to swap what comes before and after the "@" symbol.

My last name is pronounced "may-zell jee".

  1. A braided (∞,2)-category from Soergel bimodules, with Yu Leon Liu, David Reutter, Catharina Stroppel, and Paul Wedrich
    To appear.

    Here is a video of a talk about this material (starting a minute or two in, due to a technical glitch). Updated slides are here -- those contain a (very sketchy) sketch of the proof, which I didn't discuss in the recorded talk.

    And here is a video of Catharina's 2022 ICM plenary address (whose accompanying survey article is here). She gives a broad overview of TQFT and categorification, and ends by putting our main theorem into that context.

undergrad researches
  1. A cubical antipodal theorem, with Kyle E. Kinneberg, Tia Sondjaja, and Francis Su, 09/02/2009
    arxiv:0909.0471, 15 pages.
    This is the result of an REU I did in the summer after my sophomore year, supervised by Francis Su.

    23 pages.
    This is the result of a summer research project I did in the summer after my freshman year, supervised by Thomas Banchoff. If it counts, this gives me an Erdős number of 4. (And if we somehow make a movie adaptation, I'll have a Bacon number of 4 too.)

  1. An invitation to higher algebra (in progress, see here for more info)
    Contracted to be published in the Cambridge University Press series Studies in Advanced Mathematics.

The Adem relations calculator is here -- brought to you, as always, by the wizardry of the kruckmachine.

I passed my qualifying exam on Friday, May 13, 2011. You can see the syllabus here.

The unoriented cobordism ring is π*(MO)=Z/2[{xn:n≠2t-1}]=Z/2[x2,x4,x5,x6,x8,x9,...].
The complex cobordism ring is π*(MU)=Z[{x2n}]=Z[x2,x4,x6,...].
