Rationality of Darmon Points Over Genus Fields of Nonmaximal Orders
Full text linkStark-Heegner points, also known as Darmon points, were introduced by H. Darmon in [11], as certain local points on rational elliptic curves, conjecturally defined over abelian extensions of real quadratic fields. The rationality conjecture for these points is only known in the unramified case, namely, when these points are specializations of global points defined over the strict Hilbert class field H+ F of the real quadratic field F and twisted by (unramified) quadratic characters of Gal(H+ F /F). We extend these results to the situation of ramified quadratic characters; we show that Darmon points of conductor c ≥ 1 twisted by quadratic characters of G+ c =Gal(H+ c /F), where H+ c is the strict ring class field of F of conductor c, come from rational points on the elliptic curve defined over H+ c

Rationality of Darmon points over genus fields of non-maximal orders
Full text linkStark–Heegner points, also known as Darmon points, were introduced by Darmon in [5] as certain local points on rational elliptic curves, conjecturally defined over abelian extensions of real quadratic fields. The rationality conjecture for these points is only known in the unramified case, namely, when these points are specializations of global points defined over the strict Hilbert class field HF+ of the real quadratic field F and twisted by (unramified) quadratic characters of Gal(Hc+/F). We extend these results to the situation of ramified quadratic characters; more precisely, we show that Darmon points of conductor c≥ 1 twisted by quadratic characters of Gc+=Gal(Hc+/F), where Hc+ is the strict ring class field of F of conductor c, come from rational points on the elliptic curve defined over Hc+
Moschus anhuiensis Wang, Hu & Yan 1982
No full text6. Anhui Musk-deer Moschus anhuiensis French: Porte-musc d'Anhui / German: Anhui-Moschustier / Spanish: Ciervo almizclero de Anhui Taxonomy. Moschus anhuiensis Wang, Hu & Yan, 1982, Changling region (31° 10’ N, 115° 53’ E, altitude 500 m), Jinzhai county, Anhui province, China. First proposed as a subspecies of M. moschiferus, this taxon was first transferred to M. berezouskii, then given species rank. Skulls of this species are metrically unlike those of any other, and cytochrome b has consistent differences from other species, and it is probably the sister species to all others except for M. moschiferus. Monotypic. Distribution. Appears to be restricted to SW Anhui. Descriptive notes. Head—body 69.6-76. 5 cm, tail 2-4 cm, shoulder height less than 50 cm, hip height less than 60 cm; weight 7.1-9. 7 kg. A small species; skull length is 14.1-14. 9 cm, with a mean of 14-38 cm. Gray-brown in color, with dense but not well-marked pale spots on the body. A neck-stripe is present. Lachrymal length is shorter than its height. Ears are darker than body. Hairs long, 38 mm on withers, 54 mm on rump. Habitat. Little is known of the typical habitat ofthis species, except that it is found in forested regions at low elevations, below 500 m. Food and Feeding. Very little is known ofits way oflife and there are no data on food habits. Breeding. Females reach sexual maturity quickly, and are able to breed in their first year. This species is more likely to have twins than singletons. Activity patterns. No data available, but probably like related species, which tend to be more active nocturnally. Movements, Home range and Social organization. No information available, but likely similar to the Forest Musk-deer. Status and Conservation. CITES Appendix II. Classified as Endangered on The IUCN Red List. Population estimates are on the order of only 700 to 800 individuals living in the wild. The distribution of the species is very limited, likely only a little over 5000 km?. This speciesis classified as Endangered in the Chinese Red List and on the First Category of State Key Protected Wildlife List in China. Protection of habitatis needed, as well as better enforcement of hunting regulations. It is not known to occur in any protected areas. There is a clear need to determine the population size, natural history, and the extent of threats to the species. Bibliography. Groves & Feng Zuojian (1986), Su Bing et al. (2001), Wang Qishan etal. (1982).Published as part of Don E. Wilson & Russell A.
