representationswhere
Representationswhere is a term used informally in mathematics and theoretical computer science to denote a framework for restricting representations to those that satisfy a given property. It is not a widely standardized notion in mainstream literature, but it appears in discussions about classification, constraint-based construction, and the study of definable families of representations.
Formal idea: Let G be a group (or more generally, an algebra, category, or other structure) and
Relation to other concepts: In categorical language, Representationswhere corresponds to a full subcategory of Rep(G) consisting
Examples: Representationswhere(G, "unitary") yields unitary representations when a compatible inner product exists; Representationswhere(G, "irreducible and dimension

Notes: The term is informal; for rigorous work, researchers typically specify the structure, property P, and
