Solution of initial-value problem for linear third-order fuzzy differential equations. Computational and Applied Mathematics, 41(8), 1-31.2238-36031807-0302http://dx.doi.org/10.1007/s40314-022-02111-xhttps://hdl.handle.net/20.500.12713/3461Every real-world physical problem is inherently based on uncertainty. It is essential to model the uncertainty then solve, analyze and interpret the result one encounters in the world of vagueness. Generally, science and engineering problems are governed by differential equations. But the parameters, variables and initial conditions involved in the system contain uncertainty due to the lack of information in measurement, observations and experiment. However, It is necessary to develop a comprehensive approach for solving differential equations in an uncertain environment. The purpose of this work is to study and investigate the fuzzy solution of linear third-order fuzzy differential equations using the concept of strongly generalized Hukuhara differentiability (SGHD). To make our analysis possible, we apply the first and second differentiability up to the third-order fuzzy derivative of the fuzzy-valued function. Moreover, we develop an important result concerning the relationship between Laplace transform of fuzzy-valued function and third-order derivative. We construct an algorithm to determine a potential solution of linear third-order fuzzy initial-value problem using the Laplace transform technique. All these solutions are represented in terms of the Mittag-Leffler function involving a single series. Furthermore, we discuss the switching points of linear third-order differential equations and their corresponding solutions in fuzzy environments. To enhance the novelty of the proposed technique, some illustrative examples are presented as applications are analyzed to visualize and support theoretical results.eninfo:eu-repo/semantics/closedAccessSwitching PointsFuzzy Initial-Value ProblemStrongly Generalized DifferentiabilityFuzzy Laplace Transformittag-Leffler Function In Single SeriesArticle418WOS:0008853065000012-s2.0-85142236732Q110.1007/s40314-022-02111-xQ2
