Abstract. Extending a previous article (with R. Paré) on adjoints for
double categories, we deal here with weak symmetric cubical
categories (of infinite dimension). Also here, a general 'cubical
adjunction' has a colax cubical functor left adjoint to a lax one.
This cannot be viewed as an adjunction in some bicategory, because
composing lax and colax morphisms destroys all comparisons. However,
as in the case of double adjunctions, cubical adjunctions live in an
interesting double category; this now consists of weak symmetric
cubical categories, with lax and colax double functors as horizontal
and vertical arrows, linked by suitable double cells.
With best regards to colleagues and friends
