Some Studies in Hemirings by the Falling Fuzzy k‐Ideals
Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 In this article, we establish the idea of falling fuzzy k‐ideals in hemirings through the falling shadow theory and fuzzy sets. We shall express the relations between fuzzy k‐ideals and falling fuzzy k‐ideals in hemirings. In particular, we shall establish different characterizations of k‐hemiregular hemirings in the perfect positive correlation and ...

Solution of Linear and Quadratic Equations Based on Triangular Linear Diophantine Fuzzy Numbers
Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 This paper is introducing a new concept of triangular linear Diophantine fuzzy numbers (TLDFNs) in a generic way. We first introduce the concept of TLDFNs and then study the arithmetic operations on these numbers. We find a method for the ranking of these TLDFNs. At the end, we formulate the linear and quadratic equations of the types A + X = B, A · X +

Complexity, Volume 2021, Issue 1, 2021., 2021 The validity of survey sampling depends on how precise the data is. The validity reduces when questionnaire contains linguistic variables and respondent has to answer in zero or one. The ambiguity in the respondent’s mind can be minimized by getting a response in an intuitionistic fuzzy sense. In this study, we proposed intuitionistic fuzzy aggregative

A Survey on Seifert Fiber Space Theorem
International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 We review the history of the proof of the Seifert fiber space theorem, as well as its motivations in 3‐manifold topology and its generalizations.

On a characterization of the lattice of subsystems of a transition system
International Journal of Mathematics and Mathematical Sciences, Volume 2006, Issue 1, 2006., 2006 It was first proved by Birkhoff and Frink, and the result now belongs to the folklore, that any algebraic lattice is up to isomorphism the lattice of subuniverses of a universal algebra. A study of subsystems of a transition system yields a new algebraic concept, that of a strongly algebraic lattice.

On chiral differential operators over homogeneous spaces
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 2, Page 83-106, 2001., 2001 We give a classification and construction of chiral algebras of differential operators over semisimple algebraic groups G and over homogeneous spaces G/N and G/P where N is a nilpotent and P a parabolic subgroup.

International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 5, Page 281-302, 2001., 2001 Recent advances in CR (Cauchy‐Riemann) geometry have raised interesting fine questions about the regularity of CR mappings between real analytic hypersurfaces. In analogy with the known optimal results about the algebraicity of holomorphic mappings between real algebraic sets, some statements about the optimal regularity of formal CR mappings between ...

Finite, primitive and euclidean spaces
International Journal of Stochastic Analysis, Volume 1, Issue 3, Page 177-196, 1988., 1988 Integer and digital spaces are playing a significant role in digital image processing, computer graphics, computer tomography, robot vision, and many other fields dealing with finitely or countable many objects. It is proven here that every finite T0‐space is a quotient space of a subspace of some simplex, i.e.

The Fr\"olicher-Nijenhuis bracket for derivation based non commutative differential forms [PDF]
, 1994 In commutative differential geometry the Fr\"olicher-Nijenhuis bracket computes all kinds of curvatures and obstructions to integrability. In \cit!{3} the Fr\"olicher-Nijenhuis bracket was developped for universal differential forms of non-commutative ...
