Adaptive selection of face coarse degrees of freedom in the BDDC and FETI-DP iterative substructuring methods
We propose a class of methods for adaptive selection of the coarse space of the BDDC and FETI-DP iterative substructuring methods. The methods work by adding coarse degrees of freedom constructed from eigenvectors associated with in...

On averaging in the domain decomposition methods
Averaging of discontinuous functions within iterative substructuring methods is studied from a new point of view. Standard approaches are first derived as special cases, and a new approach is also suggested....

On Selections of Constraints for the BDDC Method
The Balancing Domain Decomposition by Constraints (BDDC) method is an iterative substructuring domain decomposition method which uses a coarse space. The choice of coarse constraints on continuity has strong influence on convergence...

Exploration of jet substructure using iterative declustering in pp and Pb-Pb collisions at LHC energies
substructure in pp collisions at root s = 7 TeV and central Pb-Pb collisions at root s(NN) = 2.76 TeV. Jet substructure of track-based jets is explored via iterative of two-prong substructure exposed via grooming,...

BDDC for mixed-hybrid formulation of flow in porous media with combined mesh dimensions
show thatthe problem can be reduced by means of iterative substructuring. In this set-up, the global problem and the substructure problems have a symmetric saddle package for subsurface flow simulations. We study the perfo...

Study of Using Corners for BDDC in 3D
Existing algorithms for selection of corners in BDDC are studied and a new algorithm is proposed. This combines advantages of previous algorithms. The new algorithm is applied to a benchmark and an industrial problem of linear elasticity....

Substructural logics with a reflexive transitive closure modality
Reflexive transitive closure modalities represent a number of important notions, such as common knowledge in a group of agents or non-deterministic iteration of actions. Normal modal logics with such modalities are well-explored but weaker l...
