let W be with_non-empty_element set ; for a, b being Object of (W -CL_category)

the carrier of (W -CL_category) c= the carrier of (W -INF(SC)_category)
by ALTCAT_2:def 11;
then reconsider a1 = a, b1 = b as Object of (W -INF(SC)_category) ;
<^a,b^> = <^a1,b1^>
by ALTCAT_2:28;
hence
( f in <^a,b^> iff f is infs-preserving directed-sups-preserving Function of (latt a),(latt b) )
