The 10 pages that link to Character theory, each with the reason it gives.

• Representation theoryBroader topic: Characters compress representation data into functions that often determine decompositions and equivalences.

• Group representationRelated: Traces compress matrix actions into functions that often classify representations.

• Conjugacy classNarrower topic: Conjugacy classes index the rows and columns of character tables.

• Irreducible representationRelated: Characters make many irreducibility tests and decomposition calculations possible.

• Ferdinand Georg FrobeniusNarrower topic: Frobenius’s foundational results made characters a central tool in finite-group theory.

• Richard BrauerRelated: Brauer extended character methods to modular settings and linked them to ordinary characters.

• Fourier analysis on finite groupsRelated: Characters summarize representations and are especially useful for class functions.

• Maschke's theoremNarrower topic: Maschke's theorem supplies the decomposition that underpins ordinary character theory.

• Algebraic combinatoricsRelated: Characters translate permutation actions into algebraic quantities that can be computed and compared.

• Feit–Thompson theoremRelated: The proof uses character-theoretic arguments to derive strong restrictions on odd-order groups.
