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.

Pluralism in mathematics: the multiverse view in set theory
and the question of whether every mathematical statement has
a definite truth value
Abstract: I shall describe the debate on pluralism in the philosophy of set
theory, specifically on the question of whether every mathematical and
settheoretic assertion has a definite truth value. continue reading…

January 29, Time 2:00 – 4:00 PM, Room 3209
Speaker: Sergei Artemov, CUNY Graduate Center
Title: Definitive solutions of strategic games
Abstract: In his dissertation of 1950, Nash based his concept of
solution to a game on the principles that “a rational prediction
should be unique, that the players should be able to deduce and make
use of it.” In this paper, we address the issue of when Nash
expectations of a definitive solution hold and whether the Nash
Equilibrium (NE) solution concept is a match for such definitive
solutions. continue reading…

Title: Discovering Knowability: A Semantic Analysis (a joint work with S.
Artemov, just appeared in Synthese)
Abstract: We provide a semantic analysis of the wellknown knowability
paradox stemming from the ChurchFitch observation that the meaningful
knowability principle all truths are knowable, when expressed as a bimodal
principle
F > <>KF,
yields an unacceptable omniscience property all truths are known. continue reading…
