Let $C_R$, $C_{A2}$, and $b1$ be the constants appearing in the multigrid assumptions $(G3)+(R)+(A2)_\alpha$, and let $m$ denote the cycle parameter. V-cycle threshold conjecture.…

Consider an adaptive iterative linearized finite element method with a PCG solver parameter $\lambda_{PCG}$ and a Zarantonello linearization parameter $\lambda$. PCG-parameter conj…

The $N$-body dielectric spheres problem uses the continuity constant $C_{\widetilde{\mathcal{A}}}$ of the infinite-dimensional operator $\widetilde{\mathcal{A}}$ to bound the large…

Consider iterative methods applied to systems obtained with Ga discretization, where the contrast of the material coefficients is the ratio between the largest and smallest phase c…

The coefficient matrix ${\boldsymbol{\mathsf{A}}}_{{2{\boldsymbol{N}}-\boldsymbol{1}}}$ for Ga discretization can have eigenvalues outside the interval determined by the phase coef…
