Abstract We show that every smooth projective curve over a finite field $k$ admits tame morphism to the line $k$. Furthermore, we construct with no such map when is an infinite perfect of characteristic two. Our work leads refinement Belyi theorem in positive characteristic, building on results Saïdi, Sugiyama–Yasuda, and Anbar–Tutdere.

Soils with two subcurves of Soil-Water Characteristic Curve (SWCC) (dual porosity soils) might be found within various residual soils. located in different depths have confining pressure. Residual soils are the unsaturated zones due to deep groundwater table. There is a linear correlation between hydraulic properties soil area and that its properties. This study aims examine influence pressure ...
