We transfer a classical result of Tumarkin, about approximation of functions with certain rational functions, in distributional setting. This is achieved by embedding the functions from classical spaces into the space of tempered distributions.

In this paper, we consider the following nonlinear Kirchhoff type problem − ( a + \(\lambda\) \(\int\) \(\mathbb{R}\)\(^{N}\) |∇u|2dx ) Δu + V (x)u = f(u), x ∈ \(\mathbb{R}\)\(^{N}\), where N ≥ 3, a is a positive constant, \(\lambda\) \(\ge\) 0 is a parameter. Under some sufficie...

In this paper, we are concerned with the global existence of solutions to isentropic compressible Euler equations with damping in partial space-period domains. Based on the uniform energy estimates, we obtain the global existence for any spatial dimension if the initial data is s...

Let \(\Gamma_{D_{2 n}}^{C}\) and \(E(\Gamma)\) denote the conjugate graph of a dihedral group of order \(2 n(n \in \aleph)\) and the energy of a graph respectively. The sum of the absolute values of the eigenvalues of an adjacency matrix's eigenvalues is the energy of a graph. In...

The real problematic with algebraic polynomial equations is how to exactly solve any sixth and fifth degree polynomial equations. In this study, we give a new absolute method that presents a new decomposition to exactly solve a sixth degree polynomial equation, while the correspo...
