    • (edited Jan 11th 2022)

    a reference to add (here and at Wirthmüller context) when the editing functionality is back:

    We exhibit an interesting pattern of symmetry in the existence of adjoint functors between compactly generated tensor-triangulated categories, which leads to a surprising trichotomy: There exist either exactly three adjoints, exactly five, or infinitely many.
