Convergence of Dümbgen's Algorithm for Estimation of Tail Inflation

Jasha Sommer-Simpson

Given a density $f$ on the non-negative real line, Dümbgen's algorithm is a routine for finding the (unique) log-convex, non-decreasing function $ϕ^$ such that $\int\hatϕ(x)f(x)…

Barycentric Subdivision and Isomorphisms of Groupoids

Jasha Sommer-Simpson

Given groupoids $G$ and $H$ as well as an isomorphism $Ψ : Sd G ≅ Sd H$ between subdivisions, we construct an isomorphism $P:\ma…
