In this paper, we study the fractional integro-differential equation under notion of fuzziness. We consider fuzzy Volterra-Fredholm in Caputo sense and show its existence uniqueness by using fixed point theory. Further, use modified Adomian decomposition method (MADM) to determine solution proposed problem. provide some examples support our method. also graphical representation visualize behavior solutions. At end present conclusion part.

Abstract In this work, a Laplace-like transform in fuzzy environment called Yang is introduced to solve differential equations (FDEs) with the order θ ∈ (1, 2] involving Caputo fractional derivative sense of gH -differentiability. Some basic properties for integer and derivatives are also provided. Furthermore, by utilizing combination between Adomian decomposition method (ADM) method, general algorithm hybrid (HYTM) solutions FDEs nonlinear form proposed. For validity accuracy novel some...

Abstract Uncertainty always involved in our life activities because we cannot measure a physical quantity accurately. This situation has handled by fuzzy systems and differential equations. Recently, fractional equations got tremendous attention of the researchers current century these operators model real phenomenon more accurately than integer‐order fractional‐order operators. Therefore, investigate complex population dynamical under Caputo derivative. Since Laplace transform high...

There are some confusion and complexity in our everyday lives, as we live an uncertain environment. In such type of environment, accurate calculation the data finding a solution to problem is not easy job. So, fuzzy differential equations better tools model problems domain. Modeling real-world phenomenon more accurately requires operators. Therefore, investigate fractional-order Swift–Hohenberg equation concept. We study this under Caputo fractional derivative. use Sumudu transform find out...
