Abstract :
We determine the form of polynomially bounded solutions to the Loewner differential equation that is satisfied by univalent subordination chains of the form f(z,t)=e∫t0A(τ)dτz+⋯, where A:[0,∞]→L(Cn,Cn) is a locally Lebesgue integrable mapping and satisfying the condition sups≥0∫∞0 exp{∫ts[A(τ)−2m(A(τ))In]dτ}dt ∞, and m(A(t)) 0 for t≥0, where m(A)=min{Re⟨A(z),z⟩:∥z∥=1}. We also give sufficient conditions for g(z,t)=M(f(z,t)) to be polynomially bounded, where f(z,t) is an A(t)-normalized polynomially bounded Loewner chain solution to the Loewner differential equation and M is an entire function. On the other hand, we show that all A(t)-normalized polynomially bounded solutions to the Loewner differential equation are Loewner chains.
