The \(L_{p}\)-Brunn–Minkowski inequalities for variational functionals with \(0\le p<1\)

  • Jinrong Hu

摘要

The infinitesimal forms of the \(L_{p}\) L p -Brunn–Minkowski inequalities for variational functionals, such as the q-capacity, the torsional rigidity, and the first eigenvalue of the Laplace operator, are investigated for \(p \ge 0\) p 0 . These formulations yield Poincaré-type inequalities related to these functionals. As an application, the \(L_{p}\) L p -Brunn–Minkowski inequalities for torsional rigidity with \(0 \le p < 1\) 0 p < 1 are confirmed for small smooth perturbations of the unit ball.
