Mathematics

Foundations

Set theory: mathematical theories of sets, in varying consistency strengths.
Category theory: algebraic properties of collections of transformations between mathematical objects of the same type.
Mathematical logic

Number theory: properties of integers, especially primes and prime factorization.
Algebra: numerical quantities, equations, and structures.
Geometry: shapes of and spatial relationships (e.g. distance) between objects.
- Axiomatic geometry: Euclidean geometry, non-Euclidean geometries (e.g. elliptic, hyperbolic).
- Differential Geometry: distance and curvature on manifolds.
Topology: invariant property of objects under continuous transformations.
Analysis: real- and complex-valued continuous functions; operators.
Dynamical system: description of how a complex system changes over time.
Discrete math: objects that can assume only distinct, separated values.
- Graph;
- Combinatorics;

Probability and Statistics;
Optimization and Game theory;
Computation theory: tasks that are theoretically possible with computing machines, and their relative difficulty and complexity.
Numerical methods;
