Adam Białożyt, Maciej P. Denkowski, Piotr Tworzewski, Tomasz Wawak

摘要:

本文是第一个系列处理c-全纯函数定义在代数集和代数图。这些函数可以被看作是最近引入的\textit{regulous}函数的复杂对应物。在这里,我们研究他们在无穷大的增长指数。关于解析集纤维内射性的一个一般结果,结合Tworzewski和Winiarski的一个定理,给出了代数图上的c-全纯函数的增长指数的一个界,该界是由所涉及的解析集的投射度表示的.我们还证明了图的代数性等价于函数是有理函数的限制(Serre型定理)。然后,我们转向考虑一般有限的c-全纯映射代数图,我们证明了Bézout型定理。我们还研究了一个特殊的情况下,在无穷远的juojasiewicz不等式在这种设置。

英文摘要:

This paper is the first of a series dealing with c-holomorphic functions defined on algebraic sets and having algebraic graphs. These functions may be seen as the complex counterpart of the recently introduced \textit{regulous} functions. Herein we study their growth exponent at infinity. A general result on injectivity on fibres of an analytic set together with a theorem of Tworzewski and Winiarski gives a bound for the growth exponent of a c-holomorphic function with algebraic graph in terms of the projective degrees of the sets involved. We prove also that algebricity of the graph is equivalent to the function being the restriction of a rational function (a Serre-type theorem). Then we turn to considering generically finite c-holomorphic mappings with algebraic graphs and we prove a Bézout-type theorem. We also study a particular case of the Łojasiewicz inequality at infinity in this setting.
