2. Univalent subordination chains in several complex variables<br />
• T. Poreda, 1990 (starlikeness); M. Elin, S. Reich, D. Shoikhet, 2000<br />
(spirallikeness w.r.t. a linear operator).<br />
Corollary<br />
Assume k+(A) < 2m(A). If f (z, t) is an A-univalent subordination chain<br />
such that {e −tA f (·, t)}t≥0 is a normal family, then<br />
z<br />
(1 + z) 2 ≤ e−tA f (z, t) ≤<br />
z<br />
(1 − z) 2 , z ∈ Bn , t ≥ 0.<br />
