Summary LetR be aZ-graded, noetherian, integral domain. This paper deals mainly with the divisor class groups of localizations and completions
with respect to an α-adic topology (α homogeneous) ofR. Some technical results are used to study the Veronesean subrings ofR.
Riassunto SiaR un dominioZ-graduato, noetheriano. Questo articolo tratta principalmente il gruppo di classi di divisori di localizzazioni e completamenti rispetto ad una topologia α-adica (α omogeneo) diR. Alcuni risultati tecnici vengono applicati allo studio dei sottoanelli Veronesiani diR.相似文献

We define an operator-valued distribution on the circle with the expected properties (correlation functions, Hermiticity, etc.) of the logarithmic boson field in the cylinder compact picture. This is done starting from the known Krein space realization of the right and left movers on the light cone and considering its relation with the U(1)-current algebra. The relevance of this construction fortwo-dimensional conformal quantum field theory is discussed. 相似文献

The intermediate and forward gamma detectors of EHS are used to reconstructπ°'s produced by 360 GeV/cpp interactions in the Rapid Cycling Bubble Chamber (RCBC). Using thepp forwardbackward symmetry, the inclusiveπ° production cross section is obtainedσ π°=(132±11) mb. The averageπ° multiplicity is determined as a function of the charged particle multiplicity. The (1?x) dependence is given for differentp T regions. 相似文献

Sunto Si dimostrano alcuni teoremi di unicità per le equazioni non-lineari del campo elettromagnetico in un plasma in cui si tiene
conto della pressione dei corpuscoli elettrici. I teoremi sono sempre dimostrati nel caso non stazionario, anzitutto supponendo
che il plasma occupi tutto lo spazio, poi vengono estesi al caso di un dominio finito con opportune ipotesi alla frontiera.
Infine si ottengono teoremi di unicità nel caso in cui, per effetto di campo magnetico, la pressione diventa anisotropa.

The depth profile of the counterion concentration within thin polyelectrolyte films was measured in situ using contrast variant specular neutron reflectivity to characterize the initial swelling stage of the film dissolution. We find substantial counterion depletion near the substrate and enrichment near the periphery of the film extending into the solution. These observations challenge our understanding of the charge distribution in polyelectrolyte films and are important for understanding film dissolution in medical and technological applications. 相似文献

Voltage-sensitive blockage by ADP, ATP and phytate (IP6) demonstrates that active-site contraction toward the middle of newly synthesized rigid-rod beta-barrels provides a general strategy to rationally create and modulate the voltage sensitivity (and to increase the efficiency) of molecular recognition by synthetic multifunctional pores. 相似文献

The absolute configuration of the asymmetric carbons and the axial chirality of the natural mold metabolite cercosporin (from .) have been established on the basis of X-ray analysis and chemical reactions. The results confirm the inherent dissymmetry of the perylenequinone ring, the twisting of which gives rise to the diastereoisomer isocercosporin. The energy barrier for the conversion of cercosporin into isocercosporin has been evaluated. 相似文献

Sunto Si dimostra, per le equazioni del moto dei fluidi, un teorema di unicità valido in domini illimitati, senza supporre condizioni
di convergenza all’infinito per la velocità.
