Abstract

UDC 517.5

Let UmCm be а unit ball centered at the origin and let Pn be an n-dimensional  complex projective space with the metric EPn. Also, let φ:[0,1)(0,) be a smoothly increasing function.  A holomorphic mapping f:UmPn  is called {\it φ-normal} if (φ( is bounded above for z\in\mathbb{U}^m and \xi\in\mathbb{C}^m such that \|\xi\|=1, where df(z) is the map from T_z\big(\mathbb{U}^m\big) to T_{f(z)}\big(\mathbb{P}^n\big) induced by f. For n=1, f is called a \varphi-normal function. We present an extension of Lappan's five-valued theorem to  the class of \varphi-normal functions.
