Title: Quantitative Equational Logic
Abstract: Equations are at the heart of mathematical reasoning and
reasoning with equations is the subject of equational logic. There are
some landmark results in equational logic due to Birkhoff: the
completeness theorem and the variety theorem. In the closely related
subject of universal algebra there are results about algebraic
structures defined equationally. Among these a major result is the
existence of free algebras satisfying a universal property. In
categorical terms, one can define monads on SET whose Eilenberg-Moore
category gives the algebras and whose Kleisli category defines the free
algebras. Together with Gordon Plotkin and Radu Mardare, we developed a
theory of approximate equational reasoning by introducing the symbol =ε
where ε is a (small) real number. One should think of s =ε t as meaning
that s and t are within ε in some suitable sense. It turns out that one
can define the notion of approximate equational reasoning and prove an
analogue of the completeness theorem and the variety theorem. One can
also define a quantitative algebra, which is an algebra equipped with a
metric and give a construction of free algebras. This time the
categorical description amounts to defining monads on EMET, the category
of extended metric spaces and nonexpansive maps. More important than the
theory is the existence of interesting examples that are very pertinent
for probabilistic reasoning. There have been several interesting
developments since the original paper in 2016. I will mention some of
these but will not go into depth. Our work was aided by the
contributions of Giorgio Bacci who played a major role in some of the
later developments.

TOPOLOGY, ALGEBRA AND CATEGORIES IN LOGIC (TACL 2022)
First announcement
===================================================
Conference: June 20-24, 2022 in Coimbra
School: June 13-18, 2022 in Praia de Mira
https://www.mat.uc.pt/~tacl2022 <https://www.mat.uc.pt/~tacl2022>
Organized by the Centre for Mathematics (CMUC) and the Department of Mathematics (DMUC) of the University of Coimbra
Scope
--------
Studying logic via semantics is a well-established and very active branch of mathematical logic with many applications in
computer science and elsewhere. The area is characterized by results, tools and techniques stemming from various fields,
including universal algebra, topology, category theory, order, and model theory. The programme of the conference TACL 2022 will
focus on three interconnecting mathematical themes central to the semantic study of logic and their applications: topological,
algebraic, and categorical methods.
TACL 2022 is the tenth conference in the series Topology, Algebra and Categories in Logic (TACL, formerly TANCL).
Earlier instalments of this conference have been organized in Tbilisi (2003), Barcelona (2005), Oxford (2007),
Amsterdam (2009), Marseille (2011), Nashville (2013), Ischia (2015), Prague (2017), and Nice (2019).
Featured topics

Contributed talks are intended to be about topological, algebraic or categorical methods used in mathematical or computer science
logic. This includes, but is not limited to, the following areas:
* Algebraic logic
