Each of the following conditions is sufficient for guaranteeing that a functor 𝒜 → ℬ \mathcal{A} \to \mathcal{B} preserves biproducts (where 𝒜 \mathcal{A} and ℬ \mathcal{B} are categories with a zero object):. The functor preserves finite products (for instance, because it’s a right adjoint) and any product in ℬ \mathcal{B} is a biproduct. diamond horse ranch south dakota https://bear4homes.com

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 … WebThis biproduct is often written A 1 ⊕ ··· ⊕ A n, borrowing the notation for the direct sum. This is because the biproduct in well known preadditive categories like Ab is the direct sum.
