Keywords: | Heyting semilattice; Ideal; subfitness; Open and complete ideals and homomorphisms | Issue Date: | 2007 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 07-05 (2007) | Abstract: | Subfitness and its relation to openness and completeness is studied in the context of Heyting semilattices. A formally weaker condition (c-subfitness) is shown to be necessary and su±cient for openness and completeness to coincide. For a large class of spatial frames, c-subfit = subfit. | URI: | https://hdl.handle.net/10316/11307 | Rights: | openAccess |
