Abstract:
Cichon’s diagram describes the connections between
combinatorial notions related to measure, category,
and compactness of sets of irrational numbers.
In the second part of the 2010’s decade,
Goldstern, Kellner and Shelah constructed a forcing model of
Cichon’s Maximum (meaning that all non-dependent
cardinal characteristics are pairwise different) by using large cardinals.
Some years later, we eliminated this large cardinal assumption.
In this mini-course, we explore the forcing techniques
to construct the Cichon’s Maximum model and much more.
Concretely, we discuss the following components:
1. (Nov 30th) Tukey connections and cardinal characteristics of the
continuum
2. (Dec 7th) Review of FS (finite support) iterations and
basic methods to modify cardinal characteristics.
3. (Dec 14th) Preservation theory for cardinal characteristics.
4. (Jan 11th) FS iterations with measures and ultrafilters on the natural
numbers.
5. (Jan 18th) Boolean Ultrapowers.
6. (Jan 25th) Forcing Intersected with submodels.

2nd Call for Papers
*The Connectives in Logic and Language*
4th Tsinghua Interdisciplinary Workshop on Logic, Language and Meaning (TLLM
2024)
*Extended Deadline for 2-page abstracts: November 25, 2023*
Workshop: March 30–31, 2024; Tutorials March 29, 2024.
Venue: Tsinghua University, Beijing.
Workshop web site: http://tsinghualogic.net/JRC/tllm/2024connectives/
The propositional connectives – *and, or, not, if-then,* etc. – are
fundamental building blocks in formal as well as natural languages. In the
Western tradition, they were first studied as such by the Stoics, and
*Propositional Logic* is the fundament of practically all current
systems of logic; every beginning logic course starts with it. Still,
the proof theory and
semantics of systems of propositional logic are far from trivial, and have
been studied intensely by logicians in the last one and a half century, not
least in recent decades. It is actually a vast area of research, as
witnessed by Lloyd Humberstone’s 1500 page tome *The Connectives* (2011),
which overviews much of that research. Perhaps the most familiar recent
work in this area concerns *conditionals* in formal and natural languages.
In this workshop we also focus on the apparently simpler connectives
expressing (various versions of) conjunction, disjunction, and negation.
Researchers working from a cross-linguistic perspective also focus on how
the connectives are encoded in different languages, and ask whether
classical logic is capable of capturing the variations and
universals exhibited. Even in well-studied languages like English, there
are intricate phenomena that remain challenging for classical logic,
including free choice disjunction, non-boolean conjunction, metalinguistic
negation, to name just a few. There is also growing interest in the
acquisition and processing of natural language connectives. In the context
of the hotly discussed Large Language Models (LLMs), understanding
connectives presents novel challenges that deserve in-depth exploration.
The idea behind the TLLM workshops is to bring together logicians and
linguists around a specific theme of common interest. Thus, we welcome
contributions on any general or particular aspect of the propositional
connectives in logic or language. Below are just a few examples of possible
topics for this workshop.
- semantics of negation: classical, non-classical, contra-classical
- inclusive versus exclusive disjunction in natural languages
- the meaning of connectives: model-theoretic, proof-theoretic,
game-theoretic,…
- non-classical connectives: in intuitionistic logic, linear logic,
relevance logic, orthologic, etc.
- free choice disjunction
- boolean and non-boolean conjunction
- acquisition of natural language connectives
- cross-linguistic variations of natural language connectives
- role of Large Language Models (LLMs) in understanding connectives:
challenges, capabilities, and implications

***** The Final Call for Papers (Deadline Extended) *****
Due to some request, the submission deadline is extended to
15th November, 2023.
************************************************************
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: 15th November 2023 (Extended)
All inquiries should be sent to rap(a)myukk.org .
