WebApr 10, 2024 · The celebrated Faber–Krahn inequality states that the lowest eigenvalue Λ 1 = Λ 1 (Ω) is minimized by a ball, among all sets of given volume. By the classical isoperimetric inequality, it follows that the ball is the minimizer under the perimeter constraint too. The optimality of the ball extends to repulsive Robin boundary conditions, … In mathematics the symmetrization methods are algorithms of transforming a set $${\displaystyle A\subset \mathbb {R} ^{n}}$$ to a ball with equal volume and centered at the origin. B is called the symmetrized version of A, usually denoted . These algorithms show up in solving the classical isoperimetric inequality problem, which asks: Given all two-dimensional shapes of a given area, which of them has the minimal perimeter (for details see Isoperimetric inequality). The conjecture…
Webthe inequality is strict. There are many more generalizations involving products of more functions with more linear combinations of variables as arguments. The RRI was used in solving several kinds of optimization problems, including the isoperimet-ric inequality (that balls minimize surface area), the P olya-Szeg o inequality about Sobolev
