[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

open access: yesAngewandte Chemie, EarlyView.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.

Resonance Problems for the p-Laplacian

open access: yesJournal of Functional Analysis, 1999
Using variational arguments the authors prove the existence of a weak solution for the boundary value problem \[ \begin{cases} -\Delta_p u-\lambda|u|^{p-2}u+f(x,u)=0\quad&\text{in }\Omega,\\ u=0\quad&\text{on }\partial\Omega,\end{cases} \] where \(\Delta_p u=\)div\((|Du|^{p-2}Du)\), \(p>1\), \(\Omega\) is a bounded domain of \(\mathbb R^N\), \(\lambda ...

Asymmetric critical p-Laplacian problems [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2018
We obtain nontrivial solutions for two types of critical $p$-Laplacian problems with asymmetric nonlinearities in a smooth bounded domain in ${\mathbb R}^N,\, N \ge 2$. For $p < N$, we consider an asymmetric problem involving the critical Sobolev exponent $p^\ast = Np/(N - p)$.

The Preparatory (Anti)Bonding Character of Molecular Orbitals

open access: yesAdvanced Science, EarlyView.
Herein, a concept to qualitatively predict changes in bond dissociation energies upon reduction or oxidation of molecular compounds is introduced. Changing the population of so‐called preparatory molecular orbitals influences how molecular fragments are relaxing after bond cleavage, which is shown for isolated organometallic aluminum compounds as well ...

Ambiphilic Ligand Stabilization of Aluminum(I) Fragments: Halides, Cations, and a Hydride

open access: yesAngewandte Chemie, EarlyView.
Stabilization of elusive aluminum(I) halides in the framework of an ambiphilic ligand is reported. The unique bonding situation at the trigonal‐bipyramidal aluminum center is analyzed, and the coordination chemistry and Al(I)Br transfer reactivity of the complexes are presented.

Some Liouville theorems for the p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2002
In this paper we propose a new proof for non-linear Liouville type results concerning the $p$-Laplacian. Our method differs from the one used by Mitidieri and Pohozaev because it uses a comparison principle that can be applied to nondivergence form ...

Four-parameter bifurcation for a p-Laplacian system

open access: yesElectronic Journal of Differential Equations, 2001
We study a four-parameter bifurcation phenomenum arising in a system involving $p$-Laplacians: $$displaylines{ -Delta_p u = a phi_p(u)+ b phi_p(v) + f(a , phi_p (u), phi_p (v)) ,cr -Delta_p v = c phi_p(u) + d phi{p}(v)) + g(d , phi_p (u), phi_p (v)), }$$
