“…In ( 50) and ( 51), the constants K 0 , K h , K 0 and K h depend on the domain ( 5), ( 26), (38) and τ. It follows from ( 51) and (50), that if the function z(τ) belongs to the domain ( 5), ( 26) over the interval [0, τ]; then, it exponentially decreases over the interval τ ∈ [τ 1 , τ]. Let us fix τ, τ > τ 1 > 0 in the domain (39), so that…”
