Guaranteed lower bounds on eigenvalues of elliptic operators with a hybrid high-order method
Carstensen, Carsten; Ern, Alexandre; Puttkammer, Sophie
This paper introduces a novel hybrid high-order (HHO) method to approximate the eigenvalues of a symmetric compact differential operator. The HHO method combines two gradient reconstruction operators by means of a parameter ...
