| Research Abstract |
Combinatorics of infinite cardinals greater than or equal to aleph 2 take on a different aspect from that of aleph 1, that is, the least uncountable cardinal. In this research, we studied inherent combinatorial nature of relatively small infinite cardinals greater than or equal to aleph 2, from the aspect of its interaction with several well-known axioms of set theory and that of its influence on set-theoretic topology, and obtained several significant results in this area.
