[TYPES/announce] TYPES 2021: Call for Contributions

[Henning Basold]

                            Call for Contributions

                                  TYPES 2021
                       26th International Conference on
                         Types for Proofs and Programs
                               14 - 19 June 2021
                  Virtual and possibly Leiden, The Netherlands
                           https://types21.liacs.nl/


Background
--------------

The TYPES meetings are a forum to present new and on-going work in all
aspects of type theory and its applications, especially in formalised
and computer assisted reasoning and computer programming.

The TYPES areas of interest include, but are not limited to:

* Foundations of type theory and constructive mathematics;
* Applications of type theory (e.g., linguistics or concurrency);
* Dependently typed programming;
* Industrial uses of type theory technology;
* Meta-theoretic studies of type systems;
* Proof assistants and proof technology;
* Automation in computer-assisted reasoning;
* Links between type theory and functional programming;
* Formalising mathematics using type theory;
* Homotopy type theory and univalent mathematics.

We encourage talks proposing new ways of applying type theory. In the
spirit of workshops, talks may be based on newly published papers,
work submitted for publication, but also work in progress.

Contributed Talks
--------------------

TYPES solicits contributed talks to stimulate discussions. The
contributed talks are selected on the base of extended abstracts/short
papers of 2 pages (excluding bibliography) formatted with the LaTeX
EasyChair3.5 (https://easychair.org/publications/for_authors) style.
An abstract can be based on existing, submitted or novel work, and is
not in conflict with any other forms of publication.

Submissions are handled via EasyChair:
  https://easychair.org/conferences/?conf=types2021

Upon submission, authors have to select the category of their
contribution: presentation-only talks and talks with the intent to
contribute to the post-proceedings. Presentation-only talks will
consist of a 5 minutes recorded video that is shown during the
conference in combination with 5 minutes live discussion. The purpose
of recording the talk beforehand is to avoid technical issues. Talks
with the intent for post-proceedings submission get a slot for a
10 minutes live talk plus 5 minutes discussion during the conference.
The idea is that in this case, an interactive discussion with more
in-depth feedback will help to submit to the post-proceedings.

Note that the selection at this stage only expresses an intent to
submit to the post-proceedings, and that you are neither obliged to
submit your work nor are you excluded from the submission to the
post-proceedings should you not submit an intent at this stage. The
idea is only to help you with more feedback during the conference.
Please be fair in selecting this category because the time in a
virtual conference is very limited and should be given to those
authors who really need it.

Important dates
------------------

* Submission of abstract              16 April 2021 AoE
* Author notification                 14 May 2021
* Camera-ready version of abstract    4 June 2021 AoE
* Conference                          14 - 18 June 2021

Camera-ready versions of the accepted contributions will be published
in an informal book of abstracts for distribution during the conference.

Venue
----------

This year’s TYPES will be held virtually (online), possibly in
combination with a physical meeting in Leiden in the Netherlands if the
political situation permits that. That the conference is held virtually
constraints the time of talks, and complicates exchange and
collaboration. TYPES 2021 will therefore not only consist of
presentations, but also a setup of working groups that get together
throughout the week. Every day will be split into a session of talks
and tutorials, and a collaboration session during which the working
groups will get together. The hope is that we can retain at least some
of the exchange and chatter that is the heart of the TYPES conference
series.

Attendance and Fees
-----------------------

Despite the difficulty that a virtual event brings, it also offers a
chance. We will make TYPES as inclusive as possible, which means that
attending virtually is free of charge, if you are not in the position
to pay fees. For everyone else, the fees will be low and only to cover
the costs of setting up the infrastructure and organisation. Should it
be possible that we can have a hybrid virtual-physical meeting, then
there will also be some costs for recording and streaming that will
have to be shared between local and virtual attendees. However, we
will keep these low in general and free for those who cannot afford to
pay fees.

About Types
---------------

The TYPES meetings from 1990 to 2008 were annual workshops of a
sequence of five EU funded networking projects. From 2009 to 2015,
TYPES has been run as an independent conference series. From 2016,
TYPES is partially supported by COST Action EUTypes CA15123. Previous
TYPES meetings were held in Antibes (1990), Edinburgh (1991), Båstad
(1992), Nijmegen (1993), Båstad (1994), Torino (1995), Aussois (1996),
Kloster Irsee (1998), Lökeberg (1999), Durham (2000), Berg en Dal near
Nijmegen (2002), Torino (2003), Jouy-en-Josas near Paris (2004),
Nottingham (2006), Cividale del Friuli (2007), Torino (2008),
Aussois (2009), Warsaw (2010), Bergen (2011), Toulouse (2013),
Paris (2014), Tallinn (2015), Novi Sad (2016), Budapest (2017),
Braga (2018), Oslo (2019) and Turin (2020).

Post-proceedings
-------------------

Similarly to TYPES 2011 and TYPES 2013-2020, a post-proceedings volume
will be published in the Leibniz International Proceedings in
Informatics (LIPIcs) series. Submission to that volume will be open to
everyone.

Tentative dates for post-proceedings:

* Non-binding intent (abstract)     29 October 2021
* Paper submission                  26 November 2021
* Author notification               25 March 2022

The formal call with binding dates for the post-proceedings will be
issued after the conference.
