Title: The Rival--Sands theorem for partial orders,
ascending/descending sequences, and Sigma_2 induction.
Abstract:
In their 1980 article, Rival and Sands proved two theorems inspired by
Ramsey’s theorem for pairs. The second of these theorems states that
every infinite partial order P of finite width contains an infinite
chain C with the property that every element of P is comparable either
with no element of C or with infinitely many elements of C. We show
that this theorem is equivalent to the ascending/descending sequence
principle plus the Sigma_2 induction scheme over RCA_0. This work is
joint with Marta Fiori-Carones, Alberto Marcone, and Giovanni Soldà.
どうぞよろしくお願いいたします.

皆様
京都大学の河村と申します。10月にニースで開催される
17th International Conference on Reachability Problems (RP 2023)
についてご案内させていただきます。どうぞご検討ください。
-------------------------------------------
RP 2023: CALL FOR PAPERS
-------------------------------------------
The 17th International Conference on Reachability Problems (RP'23) will
be organised by the laboratory I3S (Université Côte d'Azur, CNRS) and
LIX (Ecole Polytechnique, CNRS).
Website: https://www.lix.polytechnique.fr/RP2023
In 2020 and 2021 the conference was virtual due to COVID restrictions.
As in 2022, this year RP will be organised as a physical meeting in
Nice, offering a possibility to authors with travel restrictions to give
online presentations.
Papers presenting original contributions related to reachability
problems in different computational models and systems are being sought.
This will also be the occasion to review recent breakthroughs by
renowned invited experts and survey emerging trends and emphasise on key
open challenges. Participants are kindly encouraged to discuss core
scientific issues that need to be further tackled.
The conference proceedings will be published in Springer's Lecture Notes
in Computer Science (LNCS). A selection of articles among the
contributed papers will be invited to a special issue of a journal (TBA).
TOPICS
The conference is specifically aimed at gathering together scholars from
diverse disciplines and backgrounds interested in reachability problems
that appear in
Algebraic structures
Automata theory and formal languages
Computational game theory
Concurrency and distributed computation
Decision procedures in computational models
Graphs and dynamical networks
Hybrid dynamical systems
Logic and model checking
Verification of finite and infinite-state systems
Topics of interest include (but are not limited to):
- reachability problems in infinite-state systems,
- rewriting systems, dynamical and hybrid systems;
- reachability problems in computational games and distributed systems;
- reachability problems in dynamical networks,
- reachability problems in logic and verification;
- reachability problems in formal methods;
- reachability analysis in different computational models, counter
timed/ cellular/ communicating automata;
- Petri nets; computational and combinatorial aspects of algebraic
structures (semigroups, groups and rings);
- frontiers between decidable and undecidable reachability problems;
- predictability in iterative maps and new computational paradigms.
INVITED SPEAKERS
Confirmed:
- Nathalie Aubrun (CNRS, Paris-Saclay, France)
- Jarkko Kari (University of Turku, Finland)
- Bruno Martin (University of Nice, France)
- Shinnosuke Seki (University of Electro-Communications, Japan)
GUIDELINES FOR SUBMISSION.
THERE ARE TWO CATEGORIES OF SUBMISSIONS:
1) REGULAR PAPERS
Authors are invited to submit an extended abstract of a full paper with
at most 12 pages (excluding the bibliography and potential appendices)
formatted according to the LNCS guidelines, through EasyChair:
https://easychair.org/conferences/?conf=rp2023
2) PRESENTATION-ONLY
In addition to the formal presentations based on our LNCS proceedings
volume, we invite researchers to submit a paper which recently appeared
(or which is going to appear) in proceedings of another conference, or
which has not yet been submitted. Neither the paper nor the abstract
will be published in the proceedings.

2nd Call for Papers
***********************
Special Issue of RAP (Review of Analytic Philosophy) on 'Logics of
Communicative Interaction'
We invite submissions to a Special Issue on 'Logics of
Communicative Interaction'. This special issue will appear in the
peer-reviewed international journal called the 'Review of Analytic
Philosophy', which was first launched in 2021 as a new Open Access journal
in analytic philosophy.
This special issue welcomes new work on the logical study of dynamic
changes that take place in scenarios of communicative interaction. Complex
forms of change in cognitive states of agents and their social relations
can occur in the process of communicative interaction, which calls for a
detailed logical analysis. A central topic in such an analysis is the
triggers of such changes and their effects during the process of
communication. The triggers can include a variety of possible speech acts
while an analysis of their effect will typically zoom-in on the formal
representations of agent's doxastic and epistemic attitudes as well as the
deontic status of action types available to them. The study of such logics
for communicative interaction can be approached from different disciplines,
including logic, epistemology, argumentation theory, social choice theory,
AI, Computer Science, and Philosophy. More specifically, this special
issue welcomes work on the following topics:
- Dynamic Logics of Communication
- Logics of Speech Acts
- Logics for Belief Change and Knowledge Updates
- Dynamic Epistemic Logics
- Logical analysis of Communication in Social Networks
- Dynamic Deontic Logic
All papers will be peer reviewed according to the standards of the Journal.
Authors are advised to read the CFP of the journal downloadable from the
following page:
https://rap-journal.net/call-for-papers/ .
All the conditions specified in the CFP of the journal apply except the
condition on the publication fee: papers accepted for publication in this
special issue will be published free of charge.
Submission details:
Manuscripts should be between 8000 and 10000 words and submitted as a
double-spaced Word document or PDF file with an abstract of around 150
words. They should be fully anonymized to ensure double-blind reviewing.
Manuscripts are submitted under the understanding that they have not been
published elsewhere, either in whole or in part, and are not currently
under review elsewhere. Submissions can be made via the online submission
form at
https://rap-journal.net/submit-for-authors/
or by email attachments (rap(a)myukk.org).
If the authors intend to use LaTeX for preparing the manuscript, please use
the standard article class and submit the manuscript in the form of a PDF
file (neither the source files nor the dvi file).
Submission Deadline: 30th September 2023
All inquiries should be sent to rap(a)myukk.org .
