On the coarse-geometric detection of subgroups

Diane M. Vavrichek

We generalize [Vav] to give sufficient conditions, primarily on coarse geometry, to ensure that a subset of a Cayley graph is a finite Hausdorff distance from a subgroup. Using thi…

Upper and lower bounds for normal derivatives of spectral clusters of Dirichlet Laplacian

Xiangjin Xu

In this paper, we prove the upper and lower bounds for normal derivatives of spectral clusters $u = χ_{λ}^{s} f$ of Dirichlet Laplacian $Δ_{M}$ , $$c_s λ\|u\|_{L^2(M)} \leq \| \partial_νu \…

Perpendicular dissections of space

Thomas Zaslavsky

For each pair $(Q_{i}, Q_{j})$ of reference points and each real number $r$ there is a unique hyperplane $h ⊥ Q_{i} Q_{j}$ such that $d (P, Q_{i})^{2} - d (P, Q_{j})^{2} = r$ for points $P$ in $h$ .…
