- Make a diagram of concrete mathematical structures that I want to learn about, and related branches of mathematics.
- Survey combinatorics, especially Stanley's book and Wikipedia, for the various kinds of combinatorial constructions.
Math Notebook: Investigations
- Map of math How do math's branches, concepts and results unfold?
- Binomial theorem The heart of mathematics. In particular, the reason why there are 4 infinite families of classical Lie groups/algebras.
Challenges in Math to take on
- Understand the ways of figuring things out
- understand the binomial theorem
- explain the four classical Lie groups
- express and apply four geometries (affine, projective, conformal, symplectic) and six transformations (reflection, shear, rotation, dilation, squeeze, translation).
- relate level and metalevel in four ways to provide the basis for logic and geometry
- understand the use of variables
- Understand how math results unfold
- the relationship between the concious and the unconscious, duality, logic
- Langlands program, Poincare/Serre duality
- the association of (conscious) questions and (unconscious) answers
- theorems, and in particular, geometry theorems, Galois theory, the Fundamental Theorem of Algebra, its proofs and its centrality
- Understand the divisions of everything
- Model how God goes beyond himself
- Understand entropy as the basis for prayer
- Completely characterize an area of math such as plane geometry or chess
Open math challenges to consider
- A theory of what "equivalence" variously means
- The g-conjecture about an h-vectors of a simplicial polytope and the triangulation of a sphere.
- P vs. NP-complete
- a unifying perspective on cohomology (or has Lurie already achieved this?)
- higher order homotopy groups for sphere
