“…(Stochastic, whose basic numerical are addressed in [3,4,5,19,20,21,22, ]). Among the application areas are the biosciences, economics, materials science, medicine, public health, and robotics, in a number of these there is an underlying problem in control theory [23,24,25,26,27,28]. In this paper, we intend to study the existence, uniqueness and stability solution for the following Volterra integro-differential equations with retarded argument and symmetric matrices: The vector functions 𝑛(𝑡, 𝑥, 𝑦, 𝑧, 𝑤, 𝑣) and 𝑚(𝑡, 𝑥, 𝑦, 𝑧, 𝑤, 𝑢) is defined and continuous on the domains:…”
