My wonderful
book I suggest to buy
- G. Gerla. Fuzzy Logic: Mathematical Tools for
Approximate reasoning (Kluwer Editor).
Contents, Preface, Some pages Hajek-comment, Gottwald-comment, Gylys-comment, Belohlavek-comment,
My unfortunate paper I
suggest to read: It is an opinion paper devoted to
expose some criticisms on the actual approach to fuzzy logic. This is a
Guinness World Record paper !!! Indeed
it was submitted to six journals usually well-disposed towards fuzzy logic and it was
rejected by six journal (with no convincing motivation, in my opinion).
- G. Gerla, Compactness and effectivity for fuzzy logics:
discussing on some criticisms.

logic is used to analyze a general way to pass from a potential existent to an
actual existence.
Fuzzy
Computability and computability (The notions of recursively enumerable fuzzy
subset and decidable fuzzy subsets are defined. In accordance the possibility
for a Church thesis for fuzzy logic is discussed. Limitative theorems for fuzzy
logic are exposed).

essere una premessa per i trattamento dell’informazione di tipo probabilistico
in caso di incompletezza.

Closure
Operators and Fuzzy logic (An abstract
approach to fuzzy logic based on closure operators in accordance with Tarski’s point of view. A fuzzy logic is a continuous operators,
we call “immediate consequence operator” in the class of all fuzzy
subsets of the set of sentences of a given language. A theory is a fixed point
of such an operator)

Operators, Fuzzy Logic and Constraints (Fuzzy logic is a tool to
manage information on the truth values of the formulas, i.e. to manage
constraints on truth values)

operators and graded consequence operator. (The theory of the
fuzzy closure operators is related with the theory of graded consequences
relations)

generated by an initial valuation Busefal 41 (1989), 7-14 (The class of
necessities is considered as a closure systems)
- G. Gerla, Fuzzy Metalogic for Crisp Logics (One considers
fuzzy logics arising from a fuzzyfication of the main
metalogic notions)
Extension
Principle. (A
general extension principle for closure operators is proposed. This enables us
to extend several notion in classical mathematics to the fuzzy framework. In
particular we show that it is possible to extend any classical inferential
apparatus into a fuzzy inferential apparatus)

Operators: an extension principle. (The basic definitions)

Similarity-based
Fuzzy Logic (A
fuzzy logic is proposed in which the unification is based on the similarity
between two predicate and not on the perfect matching)

and fuzzy orders in approximate reasoning, New logic for the New economy, Ed. Scientifiche Italiane.

defines a fuzzy group and conversely)

subgroups and similarities.
- G. Gerla, Representation theorems for Fuzzy orders and Quasimetrics. (fuzzy orders are represented
as fuzzy inclusions and related with non symmetric distances. Unfortunately, I
discovered that all the results were long time proved by Dr. Ulrich Bodenhofer in a series of beatiful
papers).
- G. Gerla, Connecting fuzzy submonoids,
fuzzy preorders and quasimetrics
(any fuzzy preorder defines
a fuzzy submonoid and conversely).
Fuzzy
Control based on Fuzzy Logic Programming (One proves that
the system of rules in the implication-based and triangular norm-based fuzzy
control can be interpreted as fuzzy programs. This gives, in my opinion, a
rigorous interpretation of fuzzy control as a chapter of formal logic. Also,
this suggests several new tools and possibilities for fuzzy control)

reasoning to unify norm based and implication-based fuzzy control.

Control as a fuzzy Deduction System.

Control and Fuzzy Logic Programming by Mathematica. (An implementation in Mathematica of classical
logic programming and fuzzy logic programming is proposed)

I have an extraterrestial ancestor (Paradoxes like “Heap paradox” in fuzzy set theory,
paradox in relativity theory. To appear in a volume in honour of Vittorio Cafagna)

Infinity by Finite Sets (The infinity axiom
is satisfied by the class of finite sets)
- G. Gerla, ,
Poincaré Paradox (Poincaré paradox
about the indiscernibility. A solution of such a paradox is proposed which is
based on fuzzy logic and point-free geometry.
Point-free
Geometry (In accordance with a proposal of Whitehead in
“Process and Reality”, one consider some possible approaches to geometry in
which the regions are assumed as primitives and the points are defined by
“abstraction processes”, i.e. by considering suitable sequences of regions). I
suggest to read the expository chapter I write for the Handbook of incidence
geometry
- G. Gerla, A. Miranda, Graded
inclusion and point-free geometry. (The primitives are the regions and a graded inclusion
relation).
- L. Biacino, G. Gerla, Connection structures. (The primitives are
the regions and the connection relation, i.e. contact or overlapping relation).
- L. Biacino, G. Gerla, Connection
structures: Grzegorczyk’s and Whitehead’s Definitions
of point. (One consider different definitions of point in
point-free geometry)

geometry. (A chapter on point-free geometry from the Handbook of
incidence geometry by Buekenhout F. and Kantor W.
(1995).

Spaces. (The primitives are the
regions, the diameter and the inferior distance between regions)
- G. Gerla, R. Volpe, Geometry
Without Points. (A brief introduction)

notions of diameter and distance in the class of fuzzy subsets of a metric
space)

NOTA: Si suggerisce anche di
leggere l’interessante tesi di laurea magistrale del Dott. A. Pecoraro di cui
sono stato relatore
A. Pecoraro, Formalizzazione della geometria
senza punti di A. N. Whitehead
Modal logic
- G. Gerla, A
Note on the Principle of Predication. (One proves that the Principle of Predication in Modal
logic about De Dicto modalities is unsound)
- G. Gerla, Transformational semantics for first order
modal logic. (The claim that it “is possible A” in
the world w is interpreted as “it is
possible to transform w into a world in
which A is true”. So, any group
of transformation gives a modality).
