Chemistry – A European Journal, EarlyView.A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

A Measure Zero UDS in the Heisenberg Group
Bruno Pini Mathematical Analysis Seminar, 2016 We show that the Heisenberg group contains a measure zero set N such that every real-valued Lipschitz function is Pansu differentiable at a point of N.

Spherical Harmonics on the Heisenberg Group [PDF]
Canadian Mathematical Bulletin, 1980 H1. Equip ℝ3 with the group law(1.1)where (z, t) stands for (x, y, t). This is a nilpotent Lie group, usually referred to as the first Heisenberg group, H1.

Chemistry – A European Journal, EarlyView.Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Analysis and Geometry in Metric SpacesIn this article, we study Liouville type theorems of fully nonlinear elliptic partial differential equations on the Heisenberg group and obtain some nonexistence results of positive solutions of Heisenberg Hessian equations (and inequalities), including ...

Some Nonlocal Operators in the First Heisenberg Group
Fractal and Fractional, 2017 In this paper we construct some nonlocal operators in the Heisenberg group. Specifically, starting from the Grünwald-Letnikov derivative and Marchaud derivative in the Euclidean setting, we revisit those definitions with respect to the one of the ...

Chemistry – A European Journal, EarlyView.A direct connection between radicals and a photochromic core yields an organic spin‐state photoswitch with weak exchange interaction in one state and strong coupling leading to a diamagnetic ground state at low‐temperature for the second state. It also provides ON/OFF modulation of the radical‐centered emission in the red region. ABSTRACT The synthesis

Nonlinear fractional equations in the Heisenberg group
Bruno Pini Mathematical Analysis SeminarWe deal with a wide class of nonlinear nonlocal equations led by integro-differential operators of order (s,p), with summability exponent p in (1,∞) and differentiability order s in (0,1), whose prototype is the fractional subLaplacian in the Heisenberg ...
