7th Workshop on Formal Topology (7WFTop)-( first annoucement)
Maria Emilia Maietti
==================================
7th Workshop on Formal Topology (7WFTop).
From topology to dynamic constructivism, and back.
(first announcement)
<https://events.math.unipd.it/7wftop/>
------------------------------
The 7th Workshop on Formal Topology will take place in Venice, Italy, on April 13-17, 2026 at Convento di San Francesco della Vigna.
This is the seventh of a series of successful meetings on the development of Formal Topology and its connections with related approaches. The first six have been held in Padua (1997), Venice (2002), Padua (2007), Ljubljana (2012), Stockholm (2015), and Birmingham (2019).
The meeting is supported by Dipartimento di Matematica “Tullio Levi-Civita” (Università di Padova).
------------------------------
Dynamic
constructivism is a new approach to the foundation of
mathematics proposed by Giovanni Sambin starting from the
90s and whose forthcoming book is a first organic
exposition. The main claim is that mathematics is the
result of a dynamic, human process, which stems from the
interplay
between the
construction of mathematical entities, by abstraction and
by idealization, and their selection according to their
effectiveness in applications to reality and in the
organization of mathematics itself.
Pointfree
topology in the form of Formal Topology and the more
recent Positive Topology provides a key tool to link the
effective content of mathematics with its ideal one, and
thus achieve a synthesis of computation and visual
intuition.
A careful
management of information within a dynamic view "back and
forth" from mathematics to its foundation inevitably leads
to accepting a plural vision of mathematics, thus
enlightening connections between different constructive or
even classical approaches to it.

CONTRIBUTED TALKS
There will be room for some contributed talks. Information about abstract submission will appear soon in the website of the workshop.
ACCOMODATION
The organizers will be happy to help you find accommodation, given the peculiarities of the city of Venice, and are making agreements with some facilities to guarantee partecipants a convenient price for their stay. If you are interested, please write to the workshop email address 7wf...@math.unipd.it as soon as possible, indicating "accommodation" in the subject. Finding accommodation at a reasonable price will be difficult or virtually impossible after June-July 2025.
REGISTRATION
The registration form will be available soon on the workshop website https://events.math.unipd.it/7wftop/.
Participation will require a registration fee.
