Query: A systematic approach to reduced GLT   This paper concerns the spectral analysis of matrix-sequences that are
generated by the discretization and numerical approximation of partial
differential equations (PDEs), in case the domain is a generic Peano-Jordan
measurable set. It is observed that such matrix-sequences often present a
spectral symbol, that is a measurable function describing the asymptotic
behaviour of the eigenvalues. When the domain is a hypercube, the analysis can
be conducted using the theory of generalized locally Toeplitz (GLT) sequences,
but in case of generic domain, a new kind of matrix-sequences and theory has to
be formalized. We thus introduce the Reduced GLT sequences and symbols,
developing in full detail its theory, and presenting some application to finite
differences and finite elements discretization for
convection-diffusion-reaction differential equations.
