Intuitionistic Fuzzy Stability of Functional Equations Associated with Inner Product Spaces [PDF]

Abstract and Applied Analysis, 2011
In intuitionistic fuzzy normed spaces, we investigate some stability results for the functional equation which is said to be a functional equation associated with inner products space.

A block matrix incremental feature selection method based on fuzzy rough minimum classification error

Scientific Reports
In fuzzy rough set models, inner-product correlation serves as an effective evaluation function for feature selection, with its key advantage lying in its ability to characterize the minimum classification error inherent in the model.

On Fuzzy Soft Linear Operators in Fuzzy Soft Hilbert Spaces

Abstract and Applied Analysis, 2020
Due to the difficulty of representing problem parameters fuzziness using the soft set theory, the fuzzy soft set is regarded to be more general and flexible than using the soft set.

Fuzzy real Inner Product on Spaces of Fuzzy realn-Inner Product

Journal of Physics: Conference Series, 2018
In this work, firstly, we give two concepts about the space, that is the space of fuzzy real real inner product and the space of fuzzy real real n-inner product for all natural number n ≥ 2.

Some Properties of Fuzzy Anti-Inner Product Spaces

Iraqi Journal of Science, 2020
In this paper, the definition of fuzzy anti-inner product in a linear space is introduced. Some results of fuzzy anti-inner product spaces are given, such as the relation between fuzzy inner product space and fuzzy anti-inner product. The notion of minimizing vector is introduced in fuzzy anti-inner product settings.

Properties of Fuzzy Inner Product Spaces

International Journal of Fuzzy Logic Systems, 2014
In this paper, natural inner product structure for the space of fuzzyn−tuples is introduced. Also we have introduced the ortho vector, stochastic fuzzy vectors, ortho - stochastic fuzzy vectors, ortho-stochastic fuzzy matrices and the concept of orthogonal complement of fuzzy vector subspace of a fuzzy vector space.
