    An isoperimetric problem for leaky loops and related mean-chord inequalities

  • Original language description

    We consider a class of Hamiltonians in L-2(R-2) with attractive interaction supported by piecewise C-2 smooth loops Gamma of a fixed length L, formally given by -Delta-alpha delta(x-Gamma) with alpha>0. It is shown that the ground state of this operatoris locally maximized by a circular Gamma. We also conjecture that this property holds globally and show that the problem is related to an interesting family of geometric inequalities concerning mean values of chords of Gamma.
