Guaranteed and Sharp a Posteriori Error Estimates in Isogeometric Analysis
Stefan K. Kleiss, Satyendra K. Tomar
We present functional-type a posteriori error estimates in isogeometric analysis. These estimates, derived on functional grounds, provide guaranteed and sharp upper bounds of the e…

Algebraic Multilevel Preconditioning in Isogeometric Analysis: Construction and Numerical Studies
K. P. S. Gahalaut, S. K. Tomar, J. K. Kraus
We present algebraic multilevel iteration (AMLI) methods for isogeometric discretization of scalar second order elliptic problems. The construction of coarse grid operators and hie…
