WebAbstract. In 1877 Rayleigh conjectured that the lowest frequency of vibration of a clamped plate of given area occurs when the plate is circular. This conjecture was finally proved by Nadirashvili in 1992, with important earlier contributions due to Szegő and Talenti. An analogous conjecture concerning the critical buckling load of a clamped ...
