内容摘要:

Given a linear self-adjoint differential operator, or a compact operator, along with a discretization scheme, in several numerical applications it is crucial to understand how good the relative approximation of the whole spectrum of the discretized operator is, compared to the spectrum of the continuous operator. We present a discretization made by graphs that preserves the whole spectrum, and we will give some indications about how to apply it to some inverse problems.
