Title:

Takeuti’s finitism in the context of the Kyoto school

Abstract:

Gaisi Takeuti (1926-2017) is one of the most distinguished logicians in proof theory after Hilbert and Gentzen. He furthered the realization of Hilbert's program by formulating Gentzen's sequent calculus for higher-oder logics, conjecturing the cut-elimination theorem holds for it (Takeuti's conjecture), and obtaining several stunning results in the 1950--60's towards the solution of his conjecture.
In this talk, we aim to describe a general outline of our project to investigate Takeuti's philosophy of mathematics. In particular, we point out that there is a crucial difference between Takeuti's program and Hilbert's program, which is based on the fact that Takeuti's philosophical thinking goes back to Nishida's philosophy in Japan.
