Theorem. Isomorphisms with strict constructions [dt-003J]
The strict cpo constructions satisfy all the usual isomorphisms, including:
- (A \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } B) \times (A \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C)\;\; \simeq \;\; A \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } (B\otimes C)
- (A \otimes B \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C) \;\; \simeq \;\; A \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } (B \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C)
- (A \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C) \times (B \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C)\;\; \simeq \;\; (A\oplus B) \mathbin {\circ \hspace{-0.4em}\twoheadrightarrow } C
