## Daisuke Ikegami: On a class of maximality principles

Mathematical logic seminar – May 13 2016 Time:     12:30 – 13:30Room:     Wean Hall 8220 Speaker: Daisuke Ikegami Tokyo Denki University Japan Title:     On a class of maximality principles Abstract: The Maximality Principle (MP) states that for any first-order sentence φ in the language of set theory, if it is forced by a set forcing that φ is true in any further set generic extension, then φ must be true. continue reading…
