Abstract
AbstractUsing the notion of the so-called spectral symbol in the Generalized Locally Toeplitz (GLT) setting, we derive the GLT symbol of the sequence of matrices \(\{A_n\}\) approximating the elasticity equations. Further, as the GLT class defines an algebra of matrix sequences and Schur complements are obtained via elementary algebraic operation on the blocks of \(A_n\), we derive the symbol \(f^\mathcal {S}\) of the associated sequences of Schur complements \(\{S_n\}\) and that of its element-wise approximation.KeywordsToeplitz MatriceGlacial Isostatic AdjustmentFinite Element Method MethodBlock Toeplitz MatrixToeplitz SequenceThese keywords were added by machine and not by the authors.
