Some Epistemic Extensions of G\"odel Fuzzy Logic
In this paper, we introduce some epistemic extensions of G\"odel fuzzy logic
whose Kripke-based semantics have fuzzy values for both propositions and
accessibility relations such that soundness and completeness hold. We adopt
belief as our epistemic operator, then survey some fuzzy implications to
justify our semantics for belief is appropriate. We give a fuzzy version of
traditional muddy children problem and apply it to show that axioms of positive
and negative introspections and Truth are not necessarily valid in our basic
epistemic fuzzy models. In the sequel, we propose a derivation system as
a fuzzy version of classical epistemic logic . Next, we establish some other
epistemic-fuzzy derivation systems and which are
extensions of , and prove that all of these derivation systems are sound
and complete with respect to appropriate classes of Kripke-based models
Other Buds in Membrane Computing
It is well-known the huge Mario’s contribution to the development
of Membrane Computing. Many researchers may relate his name
to the theory of complexity classes in P systems, the research of frontiers
of the tractability or the application of Membrane Computing to
model real-life situations as the Quorum Sensing System in Vibrio fischeri
or the Bearded Vulture ecosystem. Beyond these research areas, in
the last years Mario has presented many new research lines which can
be considered as buds in the robust Membrane Computing tree. Many of
them were the origin of new research branches, but some others are still
waiting to be developed. This paper revisits some of these buds
