Abstract. Local energy error estimates for the ļ¬nite element method for elliptic problems were originally proved in 1974 by Nitsche and Schatz. These estimates show that the loca...
Lifting is a procedure for deriving valid inequalities for mixed-integer sets from valid inequalities for suitable restrictions of those sets. Lifting has been shown to be very eļ¬...
Hierarchical graph deļ¬nitions allow a modular description of graphs using modules for the speciļ¬cation of repeated substructures. Beside this modularity, hierarchical graph de...
