On the Maximal Error of Spectral Approximation of Graph Bisection
John C. Urschel, Ludmil T. Zikatanov
Spectral graph bisections are a popular heuristic aimed at approximating the solution of the NP-complete graph bisection problem. This technique, however, does not always provide a…
Stability and Monotonicity for Some Discretizations of the Biot's Model
Carmen Rodrigo, Francisco Gaspar, Xiaozhe Hu +1
We consider finite element discretizations of the Biot's consolidation model in poroelasticity with MINI and stabilized P1-P1 elements. We analyze the convergence of the fully disc…
A Finite Element Framework for Some Mimetic Finite Difference Discretizations
Carmen Rodrigo, Francisco Gaspar, Xiaozhe Hu +1
In this work we derive equivalence relations between mimetic finite difference schemes on simplicial grids and modified Nédélec-Raviart-Thomas finite element methods for model prob…
