CFA - SotFoM4: Reverse Mathematics
9 - 11 October 2017, Munich Center for Mathematical Philosophy, LMU Munich
Reverse mathematics is concerned with examining exactly which axioms are
necessary for various central mathematical theorems and results. The
program is a relatively new one in the foundations of mathematics. Its
basic goal is to assess the relative logical strengths of theorems from
ordinary (non-set-theoretic) mathematics. To this end, for a given
mathematical theorem T, one tries to find the minimal natural axiom system
that is capable of proving T. In logical terms, finding the minimal axiom
system equates to finding a collections of axioms such that each axiom
follows from T (assuming a weak base system of axioms). In doing so, one
shows that each axiom is necessary for T to hold. Because T follows from
the axioms as well, the goal of reverse mathematics is to find axiom
systems to which the theorems of ordinary mathematics are equivalent. It
turns out that most theorems are equivalent to one of five subsystems of
second order arithmetic.
The main objective of the conference is to explore the philosophical
significance of reverse mathematics as a research program in the
foundations of mathematics. The event will provide a forum for experts and
early career researchers to exchange ideas and develop connections between
philosophical and mathematical research in reverse mathematics.
Specifically, the following research questions will be addressed:
1. How are philosophical debates informed by divisions between the relevant
five subsystems of second order arithmetic, e.g., the debate between
predicativism and impredicativism?
2. How should we understand the divisions between these five systems in
terms of any natural distinctions they map on to?
3. How exhaustive are these five systems, especially in the sense of how
they map onto natural divisions?
4. How does reverse mathematics relate to and inform our understanding of
more traditional foundations of mathematics like ZFC, e.g., concerning the
existence of large cardinals?
