Intension and structure of actually infinite, rigid sets
Wujia Zhu, Yi Lin, Ningsheng Gong, Guoping Du · Kybernetes · 2008
Purpose On the basis of previous work, the authors aim to further study the problem of infinity existing in between predicates and sets. Design/methodology/approach A conceptual approach is taken in the paper. Findings The authors modify the conventional rule of thinking that each predicate determines a unique set, and establish a principle regarding the relationship between predicates and sets. Then, the authors study the structures of actually infinite, rigid sets. Originality/value The structure of actually infinite sets is detailed.
