This study presents geochemical and geochronological data from rock samples collected from the Western Carpathian mountains, eastern Slovakia. Granite assemblages that intrude the Gemeric and Veporic Superunits were imaged using a petrographic micros

In this paper we give a new upper bound for the degree of a class of transversal to infinity invariant algebraic curves for polynomial Kukles systems of arbitrary degree. Moreover, we prove that a quadratic Kukles system having at least one transvers

This paper is concerned with a predator–prey model with hyperbolic mortality and prey harvesting. The parameter regions for the stability and instability of the unique positive constant solution of ODE and PDE are derived, respectively. Especially,

In order to rule out the existence of periodic orbits in the plane for a given system of differential equations, we discuss the feature of the set of Dulac functions, establishing some of its properties as well as some results for special cases where

We provide sufficient conditions on the components of a vector field, which ensure the existence of Dulac functions depending on special functions for such vector field. We also present some applications and examples in order to illustrate our result

In this work we present an alternative method to build Dulac functions that allow one to discard the existence of periodic solutions for differential equations in the plane using partial differential equations. We give some examples to illustrate app
