Seminar organizer’s toolbox
Joel David Hamkins conducts research in mathematical logic, particularly set theory, with a focus on the mathematics and philosophy of the infinite.
He has explored the interaction of forcing and large cardinals and recently initiated the research topics known as settheoretic geology, which studies how the settheoretic universe relates to all its various ground models, and the modal logic of forcing, which explores how it relates to all its various forcing extensions.
His philosophical work on the multiverse perspective participates in the emerging debate on pluralism in the philosophy of set theory.
In addition, Hamkins has undertaken work in infinitary computability, in group theory and on the hierarchy of equivalence relations on the natural numbers under computable reducibility.
His most recent theorem is that every countable model of set theory is isomorphic to a submodel of its own constructible universe.
Professor Hamkins earned his Ph.D at the University of California at Berkeley in 1994, and holds a permanent position as Professor at The City University of New York, at the Graduate Center of CUNY and at the College of Staten Island of CUNY.
