Aaron Mazel-Gee

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

I am currently a Sherman Fairchild Instructor in Mathematics at Caltech. My office is 285 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".

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.

  2. Maximum volume space quadrilaterals, with Thomas Banchoff and Nicholas Haber, 08/02/2006
    Expeditions in Mathematics, 2 (2011), 175-198.
    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.

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,...].
