Let G be a simply connected domain in the complex plane bounded by a closed Jordan curve L and let Pn, n ≥ 0, be polynomials of respective degrees n = 0, 1,... that are orthonormal in G with respect to the area measure ...

Lommel's function s μ,ν(z) is a particular solution of the differential equation z 2y″ + zy′ + (z 2 - ν 2)y = z μ+1. Here we present estimates and monotonicity properties of the positive zeros of s μ-1/2,1/2(z) when μ ∈ ...

Two new complexes, [Zn (O2CPh)2 (L)2] · 2MeOH (1 · 2MeOH) and [Ni2(O2CPh)) 4(L)2] · 2MeCN (2 · 2MeCN), have been synthesized and characterized by X-ray analysis in the course of an ongoing investigation of the MII/X-/L[MII ...

Zinc nitride (Zn3N2) nanowires (NWs) with diameters of 50 to 100 nm and a cubic crystal structure have been grown on 1 nm Au/Al2O3via the reaction of Zn with NH3including H2between 500°C and 600°C. These exhibited an optical ...

The Aegean archipelago is a typical archipelago of continental islands which stands at the crossroads of Europe, Asia and Africa. Herein we present one of the few global studies of bioregionalization, i.e., the process of ...
