Uniform shift estimates for transmission problems and optimal rates of convergence for the parametric Finite Element Method
Hengguang Li, Victor Nistor, Yu Qiao
Let $Ω\subset \RR^d$, , be a bounded domain with piecewise smooth boundary and let be an open subset of a Banach space . Motivated by questions i…
Axisymmetric Stokes equations in polygonal domains: regularity and finite element approximations
Young Ju Lee, Hengguang Li
We study the regularity and finite element approximation of the axisymmetric Stokes problem on a polygonal domain . In particular, taking into account the singular coefficients…
Analysis of Schrödinger operators with inverse square potentials {II}: FEM and approximation of eigenfunctions in the periodic case
Eugenie Hunsicker, Hengguang Li, Victor Nistor +1
Let be a {\em periodic} potential on $\RR^3$ that is smooth everywhere except at a discrete set $\maS$ of points, where it has singularities of the form , with $ρ(x) = |…
