The paper deals with a weakly coupled system of functional-differential equations , i ∈ S, where (t,x) = (t,x₁,...,xₙ) ∈ (0,a) × G, and S is an arbitrary set of indices. Initial boundary conditions are considered and the following questions are discussed: estimates of solutions, criteria of uniqueness, continuous dependence of solutions on given functions. The right hand sides of the equations satisfy nonlinear estimates of the Perron type with respect to the unknown functions. The results are based on a theorem on extremal solutions of an initial problem for infinite systems of ordinary functional-differential equations.
