A sufficient
condition for a discrete spectrum of the Kirchhoff plate with
an infinite peak

Vol. 1 (2013), No. 2, 233–247

Abstract |
|
Sufficient conditions for a discrete spectrum of the biharmonic equation in a two-dimensional peak-shaped domain are established. Different boundary conditions from Kirchhoff’s plate theory are imposed on the boundary and the results depend both on the type of boundary conditions and the sharpness exponent of the peak. |
Keywords
