A differential inclusion : the case of an isotropic set

Gisella Croce (2005)

ESAIM: Control, Optimisation and Calculus of Variations

In this article we are interested in the following problem: to find a map $u : Ω \to ℝ^{2}$ that satisfies $\{\begin{matrix} D u \in E & a.e. in Ω \\ u (x) = ϕ (x) & x \in \partial Ω \end{matrix}$ where $Ω$ is an open set of $ℝ^{2}$ and $E$ is a compact isotropic set of $ℝ^{2 \times 2}$ . We will show an existence theorem under suitable hypotheses on $ϕ$ .

Concerning Sets of the First Baire Category with Respect to Different Metrics

Maria Moszyńska, Grzegorz Sójka (2010)

Bulletin of the Polish Academy of Sciences. Mathematics

We prove that if $ϱ_{H}$ and δ are the Hausdorff metric and the radial metric on the space ⁿ of star bodies in ℝ, with 0 in the kernel and with radial function positive and continuous, then a family ⊂ ⁿ that is meager with respect to $ϱ_{H}$ need not be meager with respect to δ. Further, we show that both the family of fractal star bodies and its complement are dense in ⁿ with respect to δ.

Continuity of the visibility function.

Ana Forte Cunto (1991)

Publicacions Matemàtiques

G. Beer defined the visibility function of a set S and proved its continuity in the interior of S. It is proved here that the visibility function of a planar Jordan domain is continuous precisely at the cone points of the boundary of S.
