Compactness of adjoints
Weba general study [BDS16] of the existence and properties of adjoints to a geomet-ric functor f : D !C between rigidly-compactly generated tensor-triangulated categories. (These de nitions will be recalled in Section2.) ... compactness locus singles out a larger subcategory than the subcategory of N-free G-spectra which can be interpreted as ... Webdefines a composition operator. Although boundedness, compactness, and other properties have been characterized for composition operators in many contexts (see [5,11], for instance), other interesting and seemingly basic problems remain open. The computation of adjoints of compo-sition operators is one of these problems [5].

If K is compact, then there exists some set of indices n1 < n2 < … < nk such that K ⊂ k ⋃ j = 1B(p, nj) = B(p, nk). As K is contained in a ball, K is bounded. Next, we show a set that is not closed is not compact.

Webcomposition operators have also been used in descriptions of adjoints of com-position operators (see [7] and the references therein). Boundedness and compactness of weighted composition operators on various Hilbert spaces of analytic functions have been studied by many mathematicians (see, for example, [4, 12, 15, 17] and references therein).
