Iftikhar Ahmad,Esther Mohr,Günter SchmidtThe construct . (resp. ..) of (separated) projection spaces and projection morphisms is shown to have limits and colimits, free objects, powerobjects, and objects representing (extremal) partial morphisms. These structures are exhibited explicitly.

Moreover, because the cocone is associated to each diagram in a uniform way, the colimit construction itself turns out to be parametric over-coming one of the limitations of ordinary parameterized specifications, this is the fixed size and structure of the formal param

Nevertheless, various approaches to first order logic with

Technically, this is handled by means of loose semantics with data constraints. Two basic kinds of refinements are used or the specification building: horizontal and vertical refinements. Horizo
