Fuzzy fixed point results and applications to ordinary fuzzy differential equations in complex valued metric spaces

Abstract

Summary: The main purpose of this article is to discuss the existence of the common solution of second-order nonlinear boundary value problems \[ \begin{cases} \mathfrak{x}''(\jmath)=\Bbbk(\jmath,\mathfrak{x}(\jmath),\mathfrak{x}'(\jmath))\quad &\text{if } \jmath \in [0,\Lambda],\quad\Lambda>0, \\ \mathfrak{x}(\jmath_1)=\mathfrak{x}_1, \\ \mathfrak{x}(\jmath_2)=\mathfrak{x}_2,\quad \jmath_1,\jmath_2 \in [0,\Lambda], \tag{0.1} \end{cases} \] where \(\Bbbk : [0,\Lambda]\times\mathfrak{S}(\mathcal{S})\times\mathfrak{S}(\mathcal{S})\rightarrow\mathfrak{S}(\mathcal{S})\) is a continuous function and \(\mathfrak{S}(\mathcal{S})\) is a family of fuzzy sets. In this regard we obtain common fixed point results for two pairs of fuzzy mappings satisfying rational contractive condition in the setting of complex valued metric spaces. Our results improve those reported in the existing literature.
