The tree model of a meromorphic plane curve
نویسنده
چکیده
We associate with a plane meromorphic curve f a tree model T (f) based on its contact structure. Then we give a description of the y-derivative of f (resp. the Jacobian J(f, g)) in terms of T (f) (resp. T (fg)). We also characterize the regularity of f in terms of its tree.

Uniqueness of meromorphic functions ans Q-differential polynomials sharing small functions
The paper concerns interesting problems related to the field of Complex Analysis, in particular, Nevanlinna theory of meromorphic functions. We have studied certain uniqueness problem on differential polynomials of meromorphic functions sharing a small function. Outside, in this paper, we also consider the uniqueness of $q-$ shift difference - differential polynomials of mero...
متن کاملFive-value rich lines, Borel directions and uniqueness of meromorphic functions
For a meromorphic function $f$ in the complex plane, we shall introduce the definition of five-value rich line of $f$, and study the uniqueness of meromorphic functions of finite order in an angular domain by involving the five-value rich line and Borel directions. Finally, the relationship between a five-value rich line and a Borel direction is discussed, that is, every Borel direction of $f$ ...
متن کاملComparison of gestational diabetes prediction with artificial neural network and decision tree models
Background: Gestational diabetes mellitus (GDM) is one of the most common metabolic disorders in pregnancy, which is associated with serious complications. In the event of early diagnosis of this disease, some of the maternal and fetal complications can be prevented. The aim of this study was to early predict gestational diabetes mellitus by two statistical models including artificial neural ne...
متن کاملGROWTH OF ENTIRE AND SUBHARMONIC ON ASYMPTOTIC CURVES t
Let f be a meromorphic, transcendental function in the finite plane having a finite number of a-points. The well-known theorem of Iversen [i, p. 224] asserts that in this case there exists a curve F going out to such that f(z) -~ a as z ~ ~, z ~ F. Such a curve is called an asymptotic curve. We henceforth make use of the standard notation from the theory of meromorphic functions [1] without spe...
متن کاملzoning of flood hazard in Nowshahr city using machine learning models
The aim of this study is to predict and model flood hazard in the city of Nowshahr, Mazandaran province using machine learning models. The criteria and indicators affecting flood hazard were identified based on the review of resources, and then the indicators were converted into rasters in ArcGIS environment, and finally standardized by fuzzy method for use in the models. K-nearest neighbor ...
