In this paper we establish some results of existence of infinitely many solutions for an elliptic equation involving the p-biharmonic and the p-Laplacian operators coupled with Navier boundary conditions where the nonlinearities depend on two real pa

We examine the semilinear resonant problem $$ -\Delta u = \lambda_1 u + \lambda g(u) \quad \text{in } \Omega,\ u\geq 0 \text{ in } \Omega, \ u_{|\partial\Omega}=0, $$ where $\Omega\subset\mathbb R^N$ is a smooth, bounded domain, $\lambda_1$ is the fi

This paper contains some results of existence of infinitely many solutions to an elliptic equation involving the p(x)-biharmonic operator coupled with Navier boundary conditions where the nonlinearities depend on two real parameters and do not posses

In this paper, we characterize those bounded from below solutions of a homogeneous wave equation on R^2 which are constant.

In this paper we give some significative counterexamples to prove that some well known generalizations of Lindelöf property are proper. Also we give some new results, we introduce and study the almost regular-Lindelof spaces as a generalization of t

Using Erdos–Rado's theorem, we show that (1) every monotonically weakly Lindelof space satisfies the property that every family of cardinality c + consisting of nonempty open subsets has an uncountable linked subfamily; (2) every monotonically Lind

The θ-closed hull of a set A in a topological space is the smallest set C containing A such that, whenever all closed neighborhoods of a point intersect C, this point is in C. We define a new topological cardinal invariant function, the θ-bitightne

A common generalization for two of the main streams of cardinality inequalities is developed; each stream derives from the famous inequality established by A.V. Arhangel'ski\u{\i} in 1969 for Hausdorff spaces. At the end of one stream is the recent i

The research in this paper is a continuation of the investigation of the cardinality of the $��$-closed hull of subsets of spaces. This research obtains new upper bounds of the cardinality of the $��$-closed hull of subsets using cardinal fun

In this article, we extend the work on minimal Hausdorff functions initiated by Cammaroto, Fedorchuk and Porter in a 1998 paper. Also, minimal Urysohn functions are introduced and developed. The properties of heredity and productivity are examined an
