Riesz basis of exponentials for a union of cubes in R^{d}
Jordi Marzo
Mathematics , 2006,
Abstract: We extend to several dimensions the result of K. Seip and Y.I. Lyubarskii that proves the existence of Riesz basis of exponentials for a finite union of intervals with equals lengths.
Marcinkiewicz-Zygmund inequalities and interpolation by spherical harmonics
Jordi Marzo
Mathematics , 2006,
Abstract: We find necessary density conditions for Marcinkiewicz-Zygmund inequalities and interpolation for spaces of spherical harmonics with respect to the L^p norm. Moreover, we prove that there are no complete interpolation families for p\neq 2.

Avanzada Científica , 2011,
Abstract: El presente artículo expone el estado del arte del Manejo Integrado de Zonas Costeras (MIZC), sobre la base de una exhaustiva revisión bibliográfica, extendiendo el estudio hasta la evolución de esta tecnología en Cuba, concluyendo cuáles son las principales oportunidades con las que cuenta este país para la aplicación del MIZC.
Some structural details of the hind wings detected in staphylinids of 7 subfamilies (Coleoptera)
Luigi De Marzo
Journal of Entomological and Acarological Research , 2010, DOI: 10.4081/jear.2010.e11
Abstract: Study of 41 species provided information as follows: (a) a setigerous lobe is located at the costal margin in every species in the subf. Staphylininae; (b) a setal comb occupies the same margin in Xantholinini and O maliinae; (c) one or more spinulae do line the anal fi eld of all O maliinae and most O xytelinae, Tachyporinae and A leocharinae; (d) number of these spinulae in A leocharinae ranges from 1 up to about 100 and is null in two species. Hypothetically, a functional importance may be attributed to both the setigerous lobe, which suggests a mechanical receptor for wing folding control, and to the f labellum-like anal fi eld of the Aleochara, which looks as a device affecting the flying trim.
A further evaluation of the sperm length in aleocharines (Coleoptera Staphylinidae)
Luigi De Marzo
Journal of Entomological and Acarological Research , 2010, DOI: 10.4081/jear.2010.e10
Abstract: and maximum values are respectively 100 μm for Aleochara intricata Mannerheim and 3.000 μm for Heterota plumbea (Waterhouse). E valuations for most species were carried out either on spermatozoa separated from the spermatheca or on bundles extracted from testes. Sperm length of Atheta inquinula was supposedly assumed as corresponding to that of the vasa deferentia. Conclusive diagrams show sperm length in some species to be disproportionate if compared with the size of the receptacle.
The Kadets 1/4 theorem for polynomials
J. Marzo,K. Seip
Mathematics , 2007,
Abstract: We determine the maximal angular perturbation of the (n+1)th roots of unity permissible in the Marcinkiewicz-Zygmund theorem on L^p means of polynomials of degree at most n. For p=2, the result is an analogue of the Kadets 1/4 theorem on perturbation of Riesz bases of holomorphic exponentials.
Sufficient conditions for sampling and interpolation on the sphere
J. Marzo,B. Pridhnani
Mathematics , 2013,
Abstract: We obtain sufficient conditions for arrays of points, $\mathcal{Z}=\{\mathcal{Z}(L) \}_{L\ge 1},$ on the unit sphere $\mathcal{Z}(L)\subset \mathbb{S}^d,$ to be Marcinkiewicz-Zygmund and interpolating arrays for spaces of spherical harmonics. The conditions are in terms of the mesh norm and the separation radius of $\mathcal{Z}(L)$.
$L^\infty$ to $L^p$ constants for Riesz projections
Jordi Marzo,Kristian Seip
Mathematics , 2010,
Abstract: The norm of the Riesz projection from $L^\infty(\T^n)$ to $L^p(\T^n)$ is considered. It is shown that for $n=1$, the norm equals $1$ if and only if $p\le 4$ and that the norm behaves asymptotically as $p/(\pi e)$ when $p\to \infty$. The critical exponent $p_n$ is the supremum of those $p$ for which the norm equals $1$. It is proved that $2+2/(2^n-1)\le p_n <4$ for $n>1$; it is unknown whether the critical exponent for $n=\infty$ exceeds $2$.
