This is a category Cwith biproduct (an operation that acts both as a distinguished product and coproduct) and a period two contravariant functor y: C!C, called the adjoint, that is compatible with the biproduct. Further results require also a symmetric monoidal tensor that is compatible with the adjoint and biproduct.

When n = 0, the given definition reads "A biproduct of the empty family is an object ⊕ i ∈ ∅ A i in C together with no morphisms, such that ⊕ i ∈ ∅ A i is a product of the empty family and ⊕ i ∈ ∅ A i is a coproduct of the empty family." A product of an empty family of objects is ...
Web$\begingroup$ This is not the correct definition of a biproduct (and in particular the theorem you cite is not true with this definition). One reason is that it does not make the biproduct unique up to unique isomorphism like a universal construction ought to be. You need to impose additional conditions to get that uniqueness (namely you need to fix the four … Categories with biproducts include: 1. The category Ab of abelian groups. More generally, any abelian category. 2. The category of (finitely generated) projective modulesover a given ring. 3. Any triangulated category, in particular the derived category of a ring, or the homotopy category of spectra. 4. The … See more A biproduct in a category 𝒞 is an operation that is both a product and a coproduct, in a compatible way. Morphisms between finite biproducts are encoded in a matrix calculus. Finite biproducts are best known from additive … See more A category C with all finite biproducts is called a semiadditive category. More precisely, this means that C has all finite products and coproducts, that the unique map 0→1 is an isomorphism (hence C has a zero object), and … See more Let 𝒞 be a category with zero morphisms; that is, C is enriched over pointed sets (which is notably the case when C has a zero object). For c1,c2 a pair of objects in C, suppose a … See more Suppose Cis an arbitrary category, without any assumption of pointedness, additivity, etc. The biproduct of c1 and c2is a tuple such that (c1⊕c2,p1,p2) is a product tuple, (c1⊕c2,i1,i2)is a coproduct tuple, and See Definition … See more
