Reaktivität von Pnictaalumenen gegenüber 1,3‐Dipol‐Molekülen

open access: yesAngewandte Chemie, EarlyView.
Pnictaalumene mit einer Pn = Al‐Mehrfachbindung unterliegen eher Azid‐ oder Diazoalken‐Insertionen als [3+2]‐Cycloadditionen. Dies führt zu AlN2Pn‐Heterocyclen, die je nach sterischem Anspruch des Azids eine große strukturelle Vielfalt aufweisen.

Prufer transformation for the p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2010
Prufer transformation is a useful tool for study of second-order ordinary differential equations. There are many possible extensions of the original Prufer transformation. We focus on a transformation suitable for study of boundary value problems for

System of degenerate parabolic p-Laplacian

open access: yesOpen Mathematics
In this article, we study the mathematical properties of the solution u=(u1,…,uk){\bf{u}}=({u}^{1},\ldots ,{u}^{k}) to the degenerate parabolic system ut=∇⋅(∣∇u∣p−2∇u),(p>2).{{\bf{u}}}_{t}=\nabla \hspace{0.25em}\cdot \hspace{0.25em}({| \nabla {\bf{u}}| }^

Intriguing Reactivity of a 1,2‐Dihydrodialumane Towards Organic Azides – From a Terminal Diazido–Dialumane to Pendulum‐Clock‐Like Azide Bridging

open access: yesAngewandte Chemie International Edition, EarlyView.
The reaction of a dihydro‐dialane supported by a hybrid ligand (DNI) with organic azides yields structurally diverse aluminium species, including the first example of low oxidation state aluminium azide complex, a diazido‐dialane, along with an aluminium‐tetrazole, and azide alumination.

A Rado type theorem for p-harmonic functions in the plane

open access: yesElectronic Journal of Differential Equations, 1994
$p$-Laplace equation $$ { m div}(|abla u|^{p-2}abla u)=0 $$ in $Omegasetminus {x :u(x)=0}$, then $u$ is a solution to the $p$-Laplacian in the whole $Omegasubset R^2$.

Resonant mixed fractional-order p-Laplacian boundary value problem on the half-line

open access: yesNonautonomous Dynamical Systems, 2021
This study aims at establishing the solvability of a fractional-order p-Laplacian boundary value problem involving both the left Caputo and right Riemann-Liouville fractional derivatives on the half-line.

On critical points of p harmonic functions in the plane

open access: yesElectronic Journal of Differential Equations, 1994
$ 1 < p < infty $, in the unit disk and equal to a polynomial $ P $ of positive degree on the boundary of this disk, then $ abla u $ has at most deg$P - 1$ zeros in the unit disk.

Resolution Enhancement by Prediction of the High-Frequency Image Based on the Laplacian Pyramid

open access: yesEURASIP Journal on Advances in Signal Processing, 2006
According to recent advances in digital image processing techniques, interest in high-quality images has been increased. This paper presents a resolution enhancement (RE) algorithm based on the pyramid structure, in which Laplacian histogram matching is

Reactivity of Pnictaalumenes Towards 1,3‐Dipole Molecules

open access: yesAngewandte Chemie International Edition, EarlyView.
Pnictaalumenes with a Pn═Al multiple bonds undergo azide or diazoalkene insertions rather than [3+2] cycloadditions. This results in AlN2P heterocycles, which show a great structural variety depending on the sterics of the azide. With TMS‐diazoalkane, thermal rearrangements afford rare cyanidoaluminates. Abstract Alkynes undergo 1,3‐dipolar cyclization
