A Multilevel Correction Scheme for Nonsymmetric Eigenvalue Problems by Finite Element Methods [PDF]
arXiv, 2015 A multilevel correction scheme is proposed to solve defective and nodefective of nonsymmetric partial differential operators by the finite element method. The method includes multi correction steps in a sequence of finite element spaces. In each correction step, we only need to solve two source problems on a finer finite element space and two ...

Quantum-assisted hλ-adaptive finite element method
Partial Differential Equations in Applied MathematicsQuantum computing is a rapidly advancing field, driven by the potential advantages derived from the unique properties of quantum entanglement. In particular, the exponential speedup of certain carefully designed algorithms, compared to their classical ...

A Study of Space-Time Discretizations for the Dirac Equation [PDF]
arXiv, 2014 We study several numerical discretization techniques for the one-space plus one-time dimensional Dirac equation, including finite difference and space-time finite element methods. Two finite difference schemes and several space-time finite elements function spaces are analyzed with respect to known analytic solutions.
