DEDEKIND TYPE SUMS ATTACHED TO DIRICHLET CHARACTERS
Kyushu Journal of Mathematics, 2004 The author considers Dedekind type sums with two Dirichlet characters and two periodic functions, and give various identities among them and their \(p\)-adic interpolating functions. In section 2, the author generalizes the Petersson-Knopp identity and its equivalent form to those Dedekind type sums, where conductors of two characters are distinct ...

Partial identification with categorical data and nonignorable missing outcomes
Canadian Journal of Statistics, EarlyView.Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Edge Fluid Turbulence Simulations of Stellarators With GRILLIX
Contributions to Plasma Physics, EarlyView.ABSTRACT The edge fluid turbulence code GRILLIX has recently been extended from axisymmetric tokamak geometries to support 3D stellarator configurations. Following successful proof‐of‐principle simulations published in Stegmeir et al., we present here a comprehensive simulation of the Wendelstein 7‐AS stellarator.
