CFP: *Extended Deadline* Symposium on the Foundations of Mathematics, Kurt
Gödel Research Center, University of Vienna, 7-8 July 2014.

Set theory is taken to serve as a foundation for mathematics. But it is
well-known that there are set-theoretic statements that cannot be settled
by the standard axioms of set theory. The Zermelo-Fraenkel axioms, with the
Axiom of Choice (ZFC), are incomplete. The primary goal of this symposium
is to explore the different approaches that one can take to the phenomenon
of incompleteness.

One option is to maintain the traditional "universe" view and hold that
there is a single, objective, determinate domain of sets. Accordingly,
there is a single correct conception of set, and mathematical statements
have a determinate meaning and truth-value according to this conception. We
should therefore seek new axioms of set theory to extend the ZFC axioms and
minimize incompleteness. It is then crucial to determine what justifies
some new axioms over others.

Alternatively, one can argue that there are multiple conceptions of set,
depending on how one settles particular undecided statements. These
different conceptions give rise to parallel set-theoretic universes,
collectively known as the "multiverse". What mathematical statements are
true can then shift from one universe to the next. From within the
multiverse view, however, one could argue that some universes are more
preferable than others.

These different approaches to incompleteness have wider consequences for
the concepts of meaning and truth in mathematics and beyond. The conference
will address these foundational issues at the intersection of philosophy
and mathematics. The primary goal of the conference is to showcase
contemporary philosophical research on different approaches to the
incompleteness phenomenon.
To accomplish this, the conference has the following general aims and
objectives:

(1) To bring to a wider philosophical audience the different approaches
that one can take to the set-theoretic foundations of mathematics.
(2) To elucidate the pressing issues of meaning and truth that turn on
these different approaches.
(3) To address philosophical questions concerning the need for a foundation
of mathematics, and whether or not set theory can provide the necessary
foundation

Date and Venue: 7-8 July 2014 - Kurt Gödel Research Center, Vienna

Confirmed Speakers: Sy-David Friedman (Kurt Gödel Research Center for
Mathematical Logic),
Hannes Leitgeb (Munich Center for Mathematical Philosophy)

Call for Papers: We welcome submissions from scholars (in particular, young
scholars, i.e. early career researchers or post-graduate students) on any
area of the foundations of mathematics (broadly construed). Particularly
desired are submissions that address the role of set theory in the
foundations of mathematics, or the foundations of set theory
(universe/multiverse dichotomy, new axioms, etc.) and related ontological
and epistemological issues. Applicants should prepare an extended abstract
(maximum 1'500 words) for blind review, and send it to sotfom [at] gmail
[dot] com. The successful applicants will be invited to give a talk at the
conference and will be refunded the cost of accommodation in Vienna for two
days (7-8 July).
