On strict higher \(C^*\)-categories. (English. French summary) Zbl 1440.18041
Summary: We provide definitions for strict involutive higher categories (a vertical categorification of dagger categories), strict higher \(C^*\)-categories and higher Fell bundles (over arbitrary involutive higher topological categories). We put forward a proposed for a relaxed form of the exchange property for higher \(C^*\)-categories that avoids the Eckmann-Hilton collapse and hence allows the construction of expolicit non-trivial “non-commutative” examples arising from the study of hypermatrices and hyper-\(C^*\)-algebras, here defined. Alternatives to the usual globular and cubical settings for strict higher categories are also explored. Applications of these non-commutative higher \(C^*\)-categories are envisaged in the study of morphisms in non-commutative geometry and in the algebraic formulation of relational quantum theory.
