Title: The game metatheorem.
Abstract: We present a new metatheorem based on Ash and Kight’s
original eta-system priority argument. The previous modification of
Ash and Knight’s metatheorem by the author was more hands-on and
slightly more general than the original. This new version is more
abstract, less hands-on, less general, but much easier to apply. We
will also mention a new topological version that is currently work in
progress with Andrew Marks.
どうぞよろしくお願いいたします.

CALL FOR CONTRIBUTIONS:
CCC 2023: Continuity, Computability, Constructivity – From Logic to
Algorithms
Research Institute for Mathematical Sciences, Kyoto University
Kyoto, Japan, September 25 - 29, 2023
Conference website: https://www.i.h.kyoto-u.ac.jp/ccc2023/
==============================================
Submission link: https://easychair.org/conferences/?conf=ccc2023
Deadline for Submissions July 31, 2023
Extended abstracts (1-2 pages) of original work should be submitted in
pdf format.
====================================================
Topics: constructive mathematics, constructive analysis, computable
analysis, exact real number computation
CCC is a workshop series that brings together researchers applying
logical methods to the development of algorithms, with a particular
focus on computation with infinite data, where issues of continuity,
computability and constructivity play major roles. Specific topics
include exact real number computation, computable analysis, effective
descriptive set theory, constructive analysis, and related areas. The
overall aim is to apply logical methods in these disciplines to provide
a sound foundation for obtaining exact and provably correct algorithms
for computations with real numbers and other continuous data, which are
of increasing importance in safety critical applications and scientific
computation.
Previous workshops have been held in Cologne 2009, Trier 2012, Gregynog
2013, Ljubljana 2014, Kochel 2015, Nancy 2017, Faro 2018, Ljubljana
2019, Faro 2020 (online), Birmingham 2021 (online), and Padova 2022.
========================================================
Invited Speakers:
Takako Nemoto (Tohoku University, Sendai, JP)
Linda Westrick (Penn State University, USA)
Alexander G. Melnikov (Victoria University of Wellington, NZ)
Siegfried M. Rump (Hamburg University of Technology, DE)
========================================================

Title: On the embedding of Kripke models into Beth models
Abstract:
Kripke showed in [1] that first-order Kripke models can be embedded
into first-order Beth models with constant domains by a sophisticated
transformation. Following [2, Chapter 13], we revisit the embedding
from modern perspectives.
