Numerical solutions of fuzzy differential equations using reproducing kernel Hilbert space method
Soft Computing, 2015This paper presents a new method for solving fuzzy differential equations based on the use of the reproducing kernel Hilbert space method under the assumption of strongly generalized differentiability. After some preliminary definitions and results , the paper introduces an overview of the theory of fuzzy differential equations.

A note on fuzzy Hilbert spaces
Journal of Intelligent & Fuzzy Systems, 2016Recently, Hasankhani et al. proved that any Felbin-fuzzy inner product space can be imbedded in a complete Felbin-fuzzy inner product space or Felbin-fuzzy Hilbert space. In this paper, it is showed a general result that any classical Hilbert space is a Felbin-fuzzy Hilbert space, so it shows that all results in classical Hilbert spaces are immediate ...

Some properties of fuzzy Hilbert spaces and norm of operators
2010The authors introduce the notion of the fuzzy inner product such that its corresponding fuzzy norm is just a fuzzy norm in the sense of \textit{J.-Z. Xiao} and \textit{X.-H. Zhu} [Fuzzy Sets Syst. 125, No.~2, 153--161 (2002; Zbl 1018.46039)] and obtain the following main results: (1) the Cauchy-Schwarz inequality holds; (2) every such fuzzy inner ...

A General Study of Fuzzy Co-Pre-Hilbert Spaces
Galoitica: Journal of Mathematical Structures and Applications, 2023This paper introduces the concepts fuzzy pre-Hilbert spaces and fuzzy co-pre-Hilbert spaces and proves some theorems in this subject. Also, it illustrates many examples to clarify the validity of the new concepts.

The emergence of fuzzy events in Hilbert space quantum theory
2004The event-structures we have studied so far (both in the abstract and in the Hilbert space situation) are typically sharp: any event always satisfies the noncontradiction principle.

Some generalizations of fuzzy soft (kˆ *– Â)-quasinormal operators in fuzzy soft Hilbert spaces
Journal of Interdisciplinary Mathematics, 2023This article is a continuation of generalizations in field operator theory in mathematics, such as we introduce new classes of fuzzy soft operator, which namely fuzzy soft (kˆ *– Â)-quasinormal operator in fuzzy soft Hilbert space, and shortly FS-(kˆ *– Â)-quasinormal operator.

Fuzzy Soft Paranormal Operator in Fuzzy Soft Hilbert Space
Communications on Applied Nonlinear AnalysisThis paper defines the fuzzy soft paranormal operator and discusses several fundamental fuzzy soft paranormal operator properties in fuzzy soft hilbert space. Some concepts relevant to the fuzzy soft paranormal operator have been defined in fuzzy soft Hilbert space.

2012
This paper presents a class of generalized global dynamical system involving (H,η) set-valued monotone mappings and a set-valued function induced by a closed fuzzy mapping in Hilbert spaces. By using the resolvent operator technique and Nadler fixed-point theorem, we prove the equilibrium point set is not empty and closed. Furthermore, we develop a new
