The novel operators are defined with three different kernels. These operators produced excellent dynamics of the chaotic systems. In this paper, the Caputo fractal-fractional operator is used to explore a chaotic system which contains only one signum function. The existence theory is developed by using the fixed-point result of Leray-Schauder to prove that the considered chaotic system possesses at least one solution. The proposed chaotic system has a unique solution, according to Banach's fixed-point theorem. We demonstrate that the suggested chaotic system is Ulam-Hyres (UH) stable under the novel operator of power law kernel by employing nonlinear functional analysis. The Adams-Bashforth technique is used to evaluate the numerical outcomes of the considered model. We show the complex structure of numerical solutions for different FO and fractal dimension values.eninfo:eu-repo/semantics/openAccessSignum FunctionChaotic SystemAdams-Bashforth MethodArticle305Q1WOS:000846027200015Q12-s2.0-8513202697310.1142/S0218348X22401399
