    Abstract Let Ω be a ball in ℝN, centered at zero, and letu be a minimizer of the nonconvex functional $$R(v) = \int_\Omega {\tfrac{1}{{1 + |\nabla v(x)|^2 }}dx} $$ over one of the classesC M := {w ∈W loc 1,∞ (∖) ∣ 0 ≤w(x) ≤M inΩ,w concave} orE M := {w ∈W loc 1,2 (Ω) ∣ 0 ≤w(x) ∖M in≤,Δw ∖ 0 inL′(∖)}of admissible functions. Thenu is not radial and not unique. Therefore one can further reduce the resistance of Newton's rotational “body of minimal resistance“ through symmetry breaking.

    Abstract. In this paper weighted Dirichlet-type inequalities for Steiner symmetrization are proved. Similar inequalities were known for the so-called starshaped rearrangements. Furthermore it is shown that the Steiner symmetrization is a mapping from $W^{1,1} _+ ({\Bbb R}^n)$ into itself.

    Abstract. Let $\Omega$ be a ball in ${\Bbb R}^N$ , centered at zero, and let $u$ be a minimizer of the nonconvex functional $$R(v)=\int_{\Omega} {1\over 1+\vert \nabla v(x)\vert^2}dx$$ over one of the classes $C_M:= \{ w\in W_{loc}^{1,\infty}(\Omega)\mid 0\leq w(x)\leq M$ in $\Omega$ , $w$ concave $\}$ or $E_M:= \{ w\in W_{loc}^{1,2}(\Omega)\mid 0\leq w(x)\leq M$ in $\Omega$ , $\Delta w\leq 0$ in ${\cal D}'(\Omega)\}$ of admissible functions. Then $u$ is not radial and not unique. Therefore one can further reduce the resistance of Newton's rotational “body of minimal resistance” through symmetry breaking.
