12 SKILL.md files are tagged “Mathematics”. They sit mostly in Mathematics & Statistics (12). Most popular: Abstract Algebra Expert, Calculus Expert, Complex Analysis Expert. Every skill is a plain-Markdown SKILL.md you can copy or download for Claude Code, Codex and other AI agents.
Abstract Algebra Expert delivers deep guidance on groups, rings, and field theory with concrete examples and a structure-first approach.
Calculus Expert guides single- and multivariable calculus with rigorous reasoning and geometric intuition, ideal for limits, differentiation, and integration problems.
Expert guidance on complex analysis, covering analytic functions, contour integration, and conformal mappings, when you need rigorous explanations.
Provides expert guidance on solving ODEs and PDEs with analytical and numerical methods; ideal when modeling dynamical systems.
Discrete Mathematics Expert solves combinatorics, graph theory, and counting problems with structured proofs and algorithmic insight for CS.
Geometry and Trigonometry Expert helps with Euclidean geometry, coordinates, and trig problems, using diagrams, invariants, and proofs.
Provides expert help with linear algebra (vectors, matrices, subspaces, eigenvalues, and linear maps) and links theory to computation for problems.
An expert in propositional/predicate logic, proof theory, and model theory who helps with rigorous proofs and foundational questions in logic.
Mathematical Modeling Expert translates real problems into mathematical models and guides analysis, simulation, validation, and interpretation when you need model-based insights.
Number Theory Expert provides explanations and guidance on divisibility, primes, modular arithmetic, and related cryptographic concepts.
Optimization Expert helps formulate and solve mathematical optimization problems (linear, convex, and combinatorial), select methods, and interpret results.
Topology Expert helps you solve questions on point-set topology, invariants, and space constructions with intuition and proofs.
