Kapalı ordinal Ramsey sayıları için bazı yeni sınırlar

Partition calculus on ordinals was introduced by Erdős and Rado and is a well-studied subject. Later on, Baumgartner extended this investigation to topological spaces and studied topological partition relations on ordinal spaces. In recent years, closed and topological partition relations on ordinals have been an active area of research. This thesis is a contribution to the study of closed ordinal Ramsey numbers. More specifically, we provide new lower and upper bounds for closed ordinal Ramsey numbers of pairs of small countable ordinals. These bounds improve the previously known bounds given by Caicedo and Hilton.
