Similarity:

We describe how find all $ℳ f_{m}$ -natural operators $D$ transforming torsion free classical linear connections $\nabla$ on $m$ -manifolds $M$ into $r$ -th order linear connections $D (\nabla)$ on $M$ .

On the eigenvalues of a Robin problem with a large parameter

Alexey Filinovskiy (2014)

Mathematica Bohemica

Similarity:

We consider the Robin eigenvalue problem $Δ u + λ u = 0$ in $Ω$ , $\partial u / \partial ν + α u = 0$ on $\partial Ω$ where $Ω \subset ℝ^{n}$ , $n \geq 2$ is a bounded domain and $α$ is a real parameter. We investigate the behavior of the eigenvalues $λ_{k} (α)$ of this problem as functions of the parameter $α$ . We analyze the monotonicity and convexity properties of the eigenvalues and give a variational proof of the formula for the derivative $λ_{1}^{'} (α)$ . Assuming that the boundary $\partial Ω$ is of class $C^{2}$ we obtain estimates to the difference $λ_{k}^{D} - λ_{k} (α)$ between the $k$ -th eigenvalue of the Laplace operator with...

A $β$ -normal Tychonoff space which is not normal

Eva Murtinová (2002)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

$α$ -normality and $β$ -normality are properties generalizing normality of topological spaces. They consist in separating dense subsets of closed disjoint sets. We construct an example of a Tychonoff $β$ -normal non-normal space and an example of a Hausdorff $α$ -normal non-regular space.
