I. Introduction. The univalent normed conformal mappings of the unit disk U={z 6 9: Izl< I}
form a complex nonlinear compactumS, lying in thelinear topological space~ of hoiomorphic
functions. The impossibility of carrying linear structures from~ over to S (a linear combination
of univalent functions can even be infinitely sheeted) complicates the construction of
variations of univalent functions, the solution of extremal problems, obtaining integral
representations, etc. Therefore, the determination of objects and structure in S with a linear …
