Reactivity of Pnictaalumenes towards 1,3‐Dipole Molecules

Angewandte Chemie International Edition, Accepted Article.
Alkynes undergo 1,3‐dipolar cyclisation reactions with organic azides giving 1,2,3‐triazoles. Pnictaalumenes RPn=AlRˈ are the isoelectronic congeners of alkynes, hence a similar reactivity towards 1,3‐dipole molecules is expected. Herein, we report the reactions of DippTerPn=AlCp* (DippTer = 2,6‑(2,6‐iPr2C6H3)‐C6H3, Cp* = [Me5C5]−, Pn = P, As) towards ...

Eigenvalues homogenization for the fractional $p-$Laplacian operator [PDF]

, 2015
In this work we study the homogenization for eigenvalues of the fractional $p-$Laplace in a bounded domain both with Dirichlet and Neumann conditions. We obtain the convergence of eigenvalues and the explicit order of the convergence rates.Comment: 12 ...

Prufer transformation for the p-Laplacian

Electronic 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 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}}| }^

Existence theorems and Hyers-Ulam stability for a class of Hybrid fractional differential equations with $p$-Laplacian operator

, 2018
In this paper, we prove necessary conditions for existence and uniqueness of solution (EUS) as well Hyers-Ulam stability for a class of hybrid fractional differential equations (HFDEs) with p-Laplacian operator.

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

Electronic 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 $Omegasubset R^2$.

Investigation of the Molecular Level Interaction in [CH3OH−CH2X2] Complexes (X=I, Br, and Cl) using Matrix‐Isolation IR Spectroscopy

Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
In CH2X2 (X=Cl, Br, and I) molecules, the magnitude of σ‐hole on the X atom decreases from CH2I2 to CH2Cl2 . Three different types of interactions i. e., C−X⋅⋅⋅O halogen bond, and C−H⋅⋅⋅O and O−H⋅⋅⋅X hydrogen bond, are possible in [CH3OH−CH2X2] complexes.

On critical points of p harmonic functions in the plane

Electronic 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.
