Fuzzy differential subordinations connected with the linear operator [PDF]
Mathematica Bohemica, 2021 We obtain several fuzzy differential subordinations by using a linear operator $\mathcal{I}_{m,\gamma}^{n,\alpha}f(z)=z+\sum\limits_{k=2}^{\infty}(1+\gamma( k-1))^nm^{\alpha}(m+k)^{-\alpha}a_kz^k$.

Fuzzy Differential Subordination for Meromorphic Function Associated with the Hadamard Product
Axioms, 2023 This paper is related to fuzzy differential subordinations for meromorphic functions. Fuzzy differential subordination results are obtained using a new operator which is the combination Hadamard product and integral operator for meromorphic function.

Fuzzy Best Dominants for Certain Fuzzy Differential Subordinations
Journal of Advances in Applied & Computational Mathematics, 2022 This paper aims to present a survey on certain fuzzy subordination properties for analytic functions defined in the open unit disk. The new results are derived by considering a certain differential operator. By making use of two differential properties of the operator we determine sufficient conditions to find the fuzzy best dominants for several fuzzy
