چکیده
At the first part of our communicate we show how specific umbral extensions of the Stirling numbers of the second kind result in new type of Dobinski-like formulas. In the second part among others one recovers how and why Morgan Ward solution of uncountable family of ψ-difference calculus nonhomogeneous equations ∆ ψ f = ϕ in the form f (x) = n≥1 B n n ψ ! ϕ (n−1) (x) + ψ ϕ(x) + p(x) extends to ψ-Appell polynomials case automatically. Illustrative specifications to q-calculus case and Fibonomial calculus case are made explicit due to the usage of upside down notation for objects of Extended Finite Operator Calculus .

متن کاملON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
متن کاملON RELATIVE CENTRAL EXTENSIONS AND COVERING PAIRS
Let (G;N) be a pair of groups. In this article, first we con-struct a relative central extension for the pair (G;N) such that specialtypes of covering pair of (G;N) are homomorphic image of it. Second, weshow that every perfect pair admits at least one covering pair. Finally,among extending some properties of perfect groups to perfect pairs, wecharacterize covering pairs of a perfect pair (G;N)...

In this note we give an example of a set Ω ⊂ R such that L(Ω) admits an orthonormal basis of exponentials { 1 |Ω|1/2 e }ξ∈Λ for some set Λ ⊂ R, but which does not tile R by translations. This improves Tao’s recent 5-dimensional example, and shows that one direction of Fuglede’s conjecture fails already in dimension 4. Some common properties of translational tiles and spectral sets are also prov...
