Choosing mathematics subject classifications

Here are Henry's tips for choosing MSC (mathematics subject classification) codes, if you're writing a paper with me!

The MSC 2020 codes are available at https://mathscinet.ams.org/msnhtml/msc2020.pdf. The MSC codes I use most frequently are as follows.

• 05E45: Combinatorics → Algebraic combinatorics → Combinatorial aspects of simplicial complexes
• 51F30: Geometry → Metric Geometry → Lipschitz and coarse geometry of metric spaces
• 52B15: Convex and discrete geometry → Polytopes and polyhedra → Symmetry properties of polytopes
• 53C23: Differential geometry → Global differential geometry → Global geometric and topological methods (à la Gromov); differential geometric analysis on metric spaces
• 54E35: General topology → Spaces with richer structures → Metric spaces, metrizability
• 55N31: Algebraic topology → Homology and cohomology theories in algebraic topology → Persistent homology and applications, topological data analysis
• 55P10: Algebraic topology → Homotopy theory → Homotopy equivalences
• 55U10: Algebraic topology → Applied homological algebra and category theory → Simplicial sets and complexes
• 57R19: Manifolds and cell complexes → Differential topology → Algebraic topology on manifolds and differential topology
• 62R40: Statistics → Statistics on algebraic and topological structures → Topological data analysis
• 68R05: Computer science → Discrete mathematics in relation to computer science → Combinatorics
