Join us for the online Logic Colloquium for a talk by Sara Uckelman (Durham):

"What Problem Did Ladd-Franklin (Think She) Solve(d)?"

Christine Ladd-Franklin is often hailed as a guiding star in the history of women in logic—not only did she study under C.S. Peirce and was one of the first women to receive a PhD from Johns Hopkins, she also, according to many modern commentators, solved a logical problem which had plagued the field of syllogisms since Aristotle. In this paper, we revisit this claim, posing and answering two distinct questions: Which
logical problem did Ladd-Franklin solve in her thesis, and which problem did she \emph{think} she solved? We show that in neither case is the answer ``a long-standing problem due to Aristotle''. Instead, what Ladd-Franklin solved was a problem due to Jevons that was first articulated in the 19th century.

Logic Supergroup talk by Stewart Shapiro (OSU/UConn) & David McCarty (Indiana)

Intuitionistic Sets and Numbers: the theory SST

SST is a small intuitionistic set theory governing the hereditarily finite sets. It is based upon set induction. Simple as SST is, it seems remarkably strong: it deduces--within intuitionistic formal logic--all the axioms of ZF + AC, less the Axiom of Infinity, except that Separation is limited to decidable predicates. It is relatively straightforward to prove that SST has the usual Goedelian incompleteness properties. SST is definitionally equivalent to full, first-order intuitionistic arithmetic, aka Heyting Arithmetic. And SST manifests the attractive metamathematical properties of many intuitionistic mathematical theories--it supports a number of different realizability and topological interpretations and can be assumed to be categorical.
