Math subject organization

This is a brief description of how my mathematical blog posts will be categorized. Although the Mathematics Subject Classification (MSC) scheme is perhaps the most official, I will be employing the same description as used by the arxiv. This means that the possible areas are the following:

  • Algebraic Geometry (math.AG)
  • Algebraic Topology (math.AT)
  • Analysis of PDEs (math.AP)
  • Classical Analysis and ODEs (math.CA)
  • Category Theory (math.CT)
  • Combinatorics (math.CO)
  • Commutative Algebra (math.AC)
  • Complex Variables (math.CV)
  • Differential Geometry (math.DG)
  • Dynamical Systems (math.DS)
  • Functional Analysis (math.FA)
  • General Mathematics (math.GM)
  • General Topology (math.GN)
  • Geometric Topology (math.GT)
  • Group Theory (math.GR)
  • History and Overview (math.HO)
  • Information Theory (math.IT)
  • K-Theory and Homology (math.KT)
  • Logic (math.LO)
  • Mathematical Physics (math.MP)
  • Metric Geometry (math.MG)
  • Numerical Analysis (math.NA)
  • Number Theory (math.NT)
  • Operator Algebras (math.OA)
  • Optimization and Control (math.OC)
  • Probability (math.PR)
  • Quantum Algebra (math.QA)
  • Representation Theory (math.RT)
  • Rings and Algebras (math.RA)
  • Spectral Theory (math.SP)
  • Statistics (math.ST)
  • Symplectic Geometry (math.SG)

Of course, I almost certainly won’t refer to all of them, but I will use many. I will also use math.REC for recreational mathematics, which I do all the time.
