Sažetak
We compute lower bounds of the Rayleigh{Ritz approximations of a part of the spectrum of an elliptic operator. Furthermore we present bounds for the accompanying Ritz vectors. The bounds include a form of a relative gap between the Ritz values and the part of the spectrum that is "not wanted". This is a joint work with Krešimir Veselić
