Interval valued (\in,\ivq)-fuzzy filters of pseudo -algebras
We introduce the concept of quasi-coincidence of a fuzzy interval value with
an interval valued fuzzy set. By using this new idea, we introduce the notions
of interval valued (\in,\ivq)-fuzzy filters of pseudo -algebras and
investigate some of their related properties. Some characterization theorems of
these generalized interval valued fuzzy filters are derived. The relationship
among these generalized interval valued fuzzy filters of pseudo -algebras
is considered. Finally, we consider the concept of implication-based interval
valued fuzzy implicative filters of pseudo -algebras, in particular, the
implication operators in Lukasiewicz system of continuous-valued logic are
discussed
The magnetic formalism; new results
We review recent results on the magnetic pseudo-differential calculus both in
symbolic and in -algebraic form. We also indicate some applications to
spectral analysis of pseudo-differential operators with variable magnetic
fields
Why most papers on filters are really trivial (including this one)
The aim of this note is to show that many papers on various kinds of filters
(and related concepts) in (subreducts of) residuated structures are in fact
easy consequences of more general results that have been known for a long time
