Approximation of nonlinear spectral problems in a Hilbert space on the parameter in a
Hilbert space. We establish the existence of eigenvalues and eigenelements. The original
Two-dimensional reductions of the cone of positive diagonal operators in ℓ2. The set of all bounded linear operators acting on the
Hilbert space is also considered. It is shown
