Hi All!

Here are my three favorite theorems.

1. The Hirsch-Smale Theorem.

2. Thom’s Theorem.

3. The Stable Parametrized H-Cobordism Theorem.

 

 

 

Here is a photo I made some years ago. I called it the “dragon julia set.” I can’t for the life of me remember the type of function that generated it, but if you do, please let me know.

I have a blog called Machine Appreciation with Maxine Calle, Thomas Brazelton, and Julian Gould.


Seminars Organized

2022-2023:  I co-oeganized the UPenn Homotopy Theory Seminar  with Thomas Brazelton.

2021-2023: I co-organized the Graduate Student Seminar with Yi Wang and Maxine Calle

 


Here are my favorite textbooks for introductions  various subjects :).

Topology: Alan Kinsey “Topology of Surfaces”

Abstract Algebra: Charles Pinter “ A book of Abstract Algebra”

Representation Theory: Ernest Vinberg “Linear Representations of Groups

Algebraic Geometry: Miles Reid  “Undergraduate Algebraic Geometry”

Homotopy Theory:  Phillip Griffiths & John Morgan “Rational Homotopy Theory and Differential forms”

Algebraic K-theory (for my manifold folks): Jonathan Rosenberg “K-theory and Geometric Topology”

A brief overview of Renee Thom’s work on cobordism and motivation for steenrod operations: Dennis sullivan

An amazing overview for methods in surgery theory: Anthony Conway “A course on Differential Topology and Surgery.”

 

Morse Theory, Complex Dynamics, Differential Topology: The one and Only John Milnor

Also here are some nice latex write ups of famous books: . TeXromancers

I especially recommend Milnor & Stasheff,  Adams Blue Book.
