“…In particular, block GLT sequences are encountered in the discretization of vectorial DEs (systems of scalar DEs) as well as in the higher-order finite element or discontinuous Galerkin approximation of scalar DEs. We refer the reader to [50,Section 10.5], [51,Section 7.3], and [20,49,75,76] for applications of the theory of GLT sequences in the context of finite difference (FD) discretizations of DEs; to [50,Section 10.6], [51,Section 7.4], and [10,20,42,49,57,67,76] for the finite element (FE) case; to [12] for the finite volume (FV) case; to [50,Section 10.7], [51,, and [36,45,46,47,48,52,57,68] for the case of isogeometric analysis (IgA) discretizations, both in the collocation and Galerkin frameworks; and to [40] for a further application to fractional DEs. We also refer the reader to [50,Section 10.4] and [1,72] for a look at the GLT approach for sequences of matrices arising from IE discretizations.…”
