Description

If 𝒜 is a concrete monoidal abelian category, show that sheaves with values in 𝒜 also form a monoidal abelian category. Prove the tensor-hom adjunction.

In fact, we only need to be able to tensor a condensed abelian group with an ordinary abelian group. This is easier: it can be done componentwise.

Research direction

Start by locating the condensed sheaf and tensor-related definitions in the repository; the issue names no files or tests. Read the existing componentwise constructions and determine what theorem statements and verification tests are needed for the monoidal structure and tensor-hom adjunction to be complete.
