Theme: Philosophy of Science and Technology, Logic
Conference Overview:
APPSA 2025, in joint collaboration with LMPST Taiwan 2025, is an
international forum that brings together scholars from Asia and
beyond. These conferences are designed to foster communication and
collaboration among scholars working in diverse areas of the
philosophy of science, the philosophy of technology, and logic.
Featuring keynote talks, contributed talks, and poster sessions, this
conference aims to advance the Asian tradition in the philosophy of
science, the philosophy of technology, and logic, and support
high-quality research in these fields. We invite submissions of
original research papers for presentation at the conference,
encouraging contributions that explore innovative perspectives and
methodologies within these fields. By promoting rigorous academic
exchange and interdisciplinary dialogue, this conference seeks to
contribute significantly to the global development of philosophical
inquiry and practice.
Topics of Interest:
Category 1: Ethics of Science and Technology
Category 2: Metaphysical or Epistemological Aspects of Science and Technology
Category 3: Historical or Social Aspects of Science and Technology
Category 4: Formal Aspects of Science and Technology (e.g., Logic,
Mathematics, and Statistics)
Category 5: Other related or interdisciplinary topics
Keynote Speakers: Michela Massimi, Sabina Leonelli, Timothy Bayne

題名:Type Theories with a Side of Effects
話者:Pierre-Marie Pédrot (INRIA Nantes)
Abstract:
Side-effects are a staple of real-world programming. Even Haskell, which
boasts about its purity, allows non-terminating programs, which is a
form of side-effects. On the other hand, dependent type theories
…
[View More]constitute a family of type systems that can be considered among the
most powerful and expressive ones. How come effectful dependent type
theories are not more pervasive? In this talk, we will give a broad
answer to this question, explaining the trade-offs at stake.

題目 A proof of Nash-Williams theorem in ATR0
概要 In [1], Crispin Nash-Williams proved that if (Q, ≤_Q) is a well
quasi-order (henceforth wqo), then so is the set of transfinite sequences
over Q with finite range, ordered by embeddability. In this talk, we will
show that this result is provable in the subsystem of second-order
arithmetic …
[View More]ATR_0: together with previous results by Shore [2], this
determines the reverse mathematical strength of Nash-Williams’ result. In
order to do this, we will go via the notion of better quasi-order, which
makes it possible to develop an equivalence between the iterated powerset
of a qo Q and the iterated powerset over Q. This is joint work with Fedor
Pakhomov.

題目 On some restricted variants of the leftmost path principle
概要 In the studies of reverse mathematics and problem reductions, principles
stating the existence of a path through a given tree play a central role.
For example, WKL, KL, C_{ω^ω} and LPP are widely studied in those contexts.
Here, WKL is the assertion that any infinite binary …
[View More]tree has a path, KL is
the assertion that any finitely branching infinite tree has a path, C_{ω^ω}
is the principle to find a path from an ill-founded tree, and LPP is the
assertion that any ill-founded tree has a leftmost path.
Recently, Towsner[Tow] introduced a new principle called the relative
leftmost path principle stating the existence of a pseudo leftmost path.
It is known that the proof-theoretic strength of relative LPP is strictly
between ATR_0 and Pi^1_1-CA_0, and relative LPP is useful to study the
complexity of some theorems which are stronger than ATR_0[FDSTY].
In this talk, I will present my contribution[SuY, Suz] to the studies of
relative LPP, and consider LPP and relative LPP restricted to WKL or KL.
A part of this talk is joint work with Keita Yokoyama.
