FoLLI meeting on the 29th of July

There will be a meeting of FoLLI on Thursday, July 29, at 18:00 CEST,
on Zoom. To join, follow links from
The meeting passcode is sent to the mailing list.

The meeting is open to all ESSLLI participants and FoLLI members.
The President of FoLLI, Larry Moss, will give a brief overview of what FoLLI
is, and announce the Annual General Meeting which will be held on
Thursday, September 9 18:00-19:00 CEST.

FoLLI Statutes and Bylaws have been unchanged for many years and need to
be updated to confirm with the Dutch legislation (FoLLI is registered in
the Netherlands). In the meeting on the 29th July, new versions of the
Statutes and Bylaws (attached) will be presented by Benedikt Löwe. The
summary of changes written by Benedikt Löwe is below.
At the AGM on the 9th of September, members of FoLLI will vote on whether to
accept the new versions.


Article 1. No changes.

Article 2. Old statutes had a paragraph that listed concrete projects some of which were obsolete (such as the book series). We removed that paragraph since it is not wise to have a specific list of concrete projects in the statutes.

Article 3. No changes.

Article 4. The 2007 statutes had removed the Vice President. The new version has restored the office of Vice President (as has been the practice of FoLLI for the last ten years).

Article 5. The 2007 had a structure of the Board that did not correspond to the current practice and also included an office called “manager of the bureau” which had not been used. The new version describes the structure of the Board precisely as it has been the practice of FoLLI in the last decade.

The 2007 allowed for postal vote for Board members, but that is not in line with Dutch law and had to be removed. (The formulation is mandatory.)

Items 5 & 6 had to be added due to Dutch legal regulations.

(Former Article 6 about the “Scientific council” was deleted since FoLLI never had such a body in practice.)

(Former Article 7 about “Working groups” was deleted since there has never been a formal working group structure.)

Article 6 (former Article 8) was adapted to current practice allowing for members to participate by video-conference with a mandatory formulation. Since Dutch law required the removal of postal votes (cf. comment on Article 5), item 6 was added which allows the Board to allow members to submit proxy votes, giving maximal flexibility tp arrange the elections within the constraints of the Dutch law.

Article 7 (former Article 9). This article was modernised and a requirement to have a proposal supported by at least five members was added.

Article 8. No changes.

Article 9. No changes.


B Y – L A W S

Article I. Sentence about the Dutch version of the Statutes added. Item about the “principal office of FoLLI” deleted since this does not exist.

Article II. Wording modified to replace the (obsolete) role of the “Manager of the Bureau” with the Secretary. A few items whose intention was unclear (about reinstatement and transferral of membership) were deleted.

The 2007 By-Laws stated that the membership list would be made available to the members; this is not in line with current privacy regulations and was deleted.

Article III. Some changes to remove inconsistencies and clarify wording. No substantial changes. An item about the quorum was removed at the request of the Notary (properly announced General Meetings are always quorate).

Article IV. A large part of this article in the 2007 By-Laws was repeating the Statutes. This text was removed and the text was adapted to be consistent with the Statutes. The “Election Committee” is a new addition.
Text relating to physical meetings of the Board was removed.

Article V. Again, text and entire items that were repeating the Statutes were deleted. The rest of the text was adapted to be consistent with the Statutes. The 2007 By-Laws had an item that allowed the Board to create new offices and appoint officers: this was removed. Instead, the new item 5. that allows the Board to delegate duties was added.

Article VI. The 2007 statutes gave “working groups” a formal statutory status; this was removed and replaced with a general statement about forming committees and working groups. Working groups still have ex officio Board members and the central role of the ESSLLI Standing Committee is now fixed in the By-Laws by item 3.

An item that referred to the Council was removed since this never existed.

Article VII. Mostly unchanged, though an item dealing with checks was deleted as obsolete.

Article VIII. No changes.

Article IX. The period of making announcements about planned changes was changed from 60 days to 15 days (to be in line with the same period for the statutes).

Aim and scope

Joachim Lambek (Dec 5, 1922 – June 23, 2014), for more than 60 years, has been a profoundly inspirational mathematician, with groundbreaking contributions to algebra, category theory, linguistics, theoretical physics, logic and proof theory. As part of the 15th Congress of Logic, Methodology and Philosophy of Science (CLMPS 2015), FoLLI organizes an Affiliated Meeting on the legacy of Joachim Lambek. Talks at the meeting will present current research in the various areas where the impact of Lambek’s work can be felt, and highlight some remarkable convergences of methods and techniques across these fields, linking category theory, deductive systems, and models of computation.

The meeting consists of two parts.

I. Foundations: logic, mathematics

The first part of the meeting is devoted to the impact of Jim Lambek’s foundational ideas on category theory, algebra, logic, proof theory and the theory of computation on current work in these areas.

II. Applications: physics, linguistics

In his latest book, From Rules of Grammar to Laws of Nature (2014), Jim Lambek’s interests in the application of mathematical ideas range from the grammatical analysis of natural languages to the use of quaternions in special relativistic quantum mechanics. The second part of the meeting is devoted to current work on resource-logical themes in theoretical physics and formal linguistics, and the connections between these two disciplines via shared categorical structures.

Celebration event in honour of Johan van Benthem, 26-27 September 2014

On 26 and 27 September 2014 ILLC and the University of Amsterdam organize a Celebration Event for Johan van Benthem, on the occasion of his official retirement from the University of Amsterdam. The first day will have lectures for the general public, Johan’s valedictory lecture, and a reception. The second day is a scientific workshop devoted to current trends in logic, with emphasis to the areas where Johan was or is active.

Friday September 26: The Impact of Logic

Venue: Aula Oude Lutherse kerk, Singel 411, Amsterdam.

Friday September 26 will bring us Lectures on the Impact of Logic by five internationally renowned speakers who all have made significant contributions to general public awareness of logic, and to the development of areas of logic related to the interests of Johan van Benthem:

The talks will be accessible to a broad audience. In the afternoon, Johan van Benthem will give his Valedictory Lecture
as University Professor of the University of Amsterdam. This is followed by speeches, a book presentation, and a reception offered by the University of Amsterdam.

Saturday September 27: Workshop on the Future of Logic

Venue: Tobacco Theater, Nes 75–87, Amsterdam

Prominent colleagues and friends of Johan van Benthem will give talks targeted at an audience specialized in logic. All colleagues and former students of Johan are invited to attend. Themes are:

  • Logic, Mathematics and Computation
    Talks by Albert Visser (Utrecht), Hajnal Andreka and Istvan Nemeti (Budapest), Balder ten Cate (Santa Cruz).
  • Logic, Language and Cognition
    Talks by Thomas Icard (Stanford), Dag Westerstahl (Gothenburg).
  • Logic and Philosophy
    Talks by Hannes Leitgeb (Munich), Wesley Holliday (Berkeley), Sergei
    Artemov (New York, Moscow).
  • Logic, Games and Argumentation
    Talks by Samson Abramsky (Oxford), Dov Gabbay (London), Giacomo Bonanno (UC Davis, California).

Saturday Evening: Buffet Dinner and Reunion Party

The workshop will be succeeded by a buffet dinner with speeches, and then by a big reunion party. The party is meant for everyone connected to ILLC or to Johan. This includes students, colleagues, collaborators, friends and family. You are all cordially invited to be there, and to help us make this a truly memorable event.

For further info on the Johan Jubilee Events we advise you to keep an eye on the dedicated website, where further details will appear.
