Generalized matrix models and AGT correspondence at all genera
Generalized matrix models AGT correspondence
2010/12/24
We study generalized matrix models corresponding to n-point Virasoro conformal blocks on Riemann surfaces with arbitrary genus g. Upon AGT correspondence, these describe four dimensional N=2 SU(2)^{n...
On isolated smooth curves of low genera in Calabi-Yau complete intersection threefolds
isolated curves deformations Hilbert schemes Calabi-Yau threefolds
2010/12/10
Building on results of Clemens and Kley, we find criteria for a continuous family of curves in a nodal K-trivial threefold Y0 to deform to a scheme of finitely many smooth isolated curves in a general...

Twenty-nine species belonging to 17 genera of the subfamily Ceutorhynchinae are reported from the Central Anatolian and the Mediterranean regions of Turkey. Detailed distributions of these species in ...
Platystrophia (Orthida) and new related Ordovician and Early Silurian brachiopod genera
Rhynchonelliformea Platystrophiidae Baltica Avalonia Laurentia new taxa
2009/10/21
More than 150 Ordovician and Early Silurian brachiopod species have been assigned to the genus Platystrophia King,1850 mainly on the basis of their Spirifer-like shell exteriors. King’s concept o...

Eastern Asian endemic seed plant genera and their paleogeographic history throughout the Northern Hemisphere
Cretaceous eastern Asia endemic paleobotany phytogeography Tertiary
2009/8/4
We review the fossil history of seed plant genera that are now endemic to eastern Asia. Although the majority of eastern Asian endemic genera have no known fossil record at all, 54 genera, or about 9%...

杉科、柏科的系统发生分析——来自28S rDNA序列分析的证据Phylogenetic Relationships among the Genera of Taxodiaceae and Cupressaceae from 28S rDNA Sequences
28S rDNA 杉科 柏科 系统发生 替代速率
2007/12/30
摘要对杉科（Taxodiaceae）与柏科（Cupressaceae s.s.）的28S rRNA基因的部分序列（约630 bp）进行PCR扩增、序列测定和系统发生关系分析，用简约法和邻接法构建的系统发生树基本一致。结果表明，杉科与柏科构成一个单系群，支持将杉科、柏科（Sciadopitys除外）合并为一个科——广义柏科（Cupressaceae sensu lato）的观点。在广义柏科中，Tai...
