The Luna-Vust Theory of Spherical Embeddings
The work of Krämer, Luna, Vust, Brion and others [Krä,LV,BLV,BP] established the importance of a very distinguished class of homogeneous varieties G/H, those which are now called spherical. Such varieties are homogeneous for a connected reductive group G and are characterized by many equivalent properties, the most important being (see [BLV]): — Any Borel subgroup B of G has an open orbit in G/...
متن کاملRemembering Eliahu de Luna Montalto (1567–1616)
Born in Portugal and the son of Marranos (Christianized Jews from Spain), Eliahu de Luna Montalto lived during a particularly harsh period for the Jewish people. Throughout Europe, the situation for Jews was unfavorable; laws had been passed forbidding them to live in England for the past 300 years, and for the past 200 years in France. Additionally, in France, while Jews were permitted to stud...
متن کاملMetallic Phases in the Luna 24 Soil Samples
The metal and sulfide phases in the Luna 24 soil samples were studied with the optical microscope and the electron microprobe. The compositions of the metal particles fall into three groups based on their Ni and Co contents: (1) Samples of meteoritic composition which have undergone metamorphism on the lunar surface. (2) Samples of submeteoritic, low Ni and low Co contents, including most of th...
متن کاملActive Annotation in the LUNA Italian Corpus of Spontaneous Dialogues
In this paper we present an active approach to annotate with lexical and semantic labels an Italian corpus of conversational human-human and Wizard-of-Oz dialogues. This procedure consists in the use of a machine learner to assist human annotators in the labeling task. The computer assisted process engages human annotators to check and correct the automatic annotation rather than starting the a...
متن کاملHydrogen Burning at the Energies of Classical Nova at Luna
cluding red giants, asymptotic giant branch (AGB) stars, massive stars, and classical novae. In particular, the ratio between reaction rates of 17O(p,α)14N (Q = 1.2 MeV) and 17O(p,γ)18F (Q = 5.6 MeV) channels on 17O is one of the most important parameters for the galactic synthesis of 17O, the stellar production of radioactive 18F, and for predicted O isotopic ratios in presolar grains. The LUN...
