All nonlinear Lipschitzian operators in Cm space constitute a seminormoperator space L(Cm). In this paper, many important properties of operator in L(Cm)are studied, include: the approximate distance from a invertable operator to the setof noninvertable operators, the converse of exponential contraction of operator, therelation between numerical range and spectrum of operator. The obtained resultsgeneralize many famous theorems of lineax operator.
