The paper gives a quick account of the simplest cases of the Hitchin integrable systems and of the Knizhnik-Zamolodchikov-Bernard connection at genus 0, 1 and 2. In particular, we construct the action-angle variables of the genus 2 Hitchin system with group SL2 by exploiting its relation to the classical Neumann integrable systems. 1 Hitchin systems As was realized by Hitchin in [16], a large f...

The genus Ceratocystis was established in 1890 and accommodates many important fungi. These include serious plant pathogens, significant insect symbionts and agents of timber degradation that result in substantial economic losses. Virtually since its type was described from sweet potatoes, the taxonomy of Ceratocystis has been confused and vigorously debated. In recent years, particulary during...

We obtain elliptic genera of monopole string in 5d MSYM. We find agreement with the corresponding TST-dual dyonic-instanton single particle indices in arXiv:1110.2175. We make use of (2,2) superconformal algebra and its spectral flow, and the agreement can therefore be taken as evidence that monopole string (4,4) sigma models are exactly quantum superconformal.

The studies were conducted during 2008–2010 to evaluate Fishery status and its bearing on socio-economic condition of Fishers Community of undivided Goalpara district of Assam. A total of 97 species belongs to 56 genera of 26 families were recorded from various fish landing centers of the region during study period. Fishers catch fish in the river throughout the year. However, fishing intensity...

Xiphydriid woodwasps have been very rarely collected in Australasia although they are widely distributed in the region. Species have been described from the Aru, Ambon and Buru Islands, Indonesia, eastern mainland Australia, Papua New Guinea, and New Zealand. Here Rhysacephala novacaledonica Jennings & Austin, sp. nov., is described, which is the first record of a xiphydriid woodwasp from New C...

What Locke devotes in his Essay to the topic of individuals and universals, and to abstraction as a way that leads from the former to the latter (II, 11, sections 9, 10, 11; II, 32, sections 7, 8; III, 3) is a watered down version of scholastic textbooks. One starts with a relation of similitude among individuals (III, 3, 13), one performs a leaving out and a retaining of features in the given ...

In this paper we survey various constructions and properties of genera and characteristic numbers of singular complex algebraic varieties. In particular, we discuss genera for the singular varieties appearing in the minimal model program, as well as those defined by Hodge theory and functorial characteristic classes.

We present an extension of the “miraculous cancellation” formulas of Alvarez-Gaumé, Witten and Kefeng Liu to a twisted version where an extra complex line bundle is involved. Relations to the Ochanine congruence formula on 8k + 4 dimensional Spinc manifolds are discussed. To cite this article: F. Han, W. Zhang, C. R. Acad. Sci. Paris, Ser.

The Family Russulaceae comprises of some important agaricoid and gasteroid taxa of Agaricomycetes. Two genera, Lactarius and Russula are distinctive basidiomycetes that possesses heteromerous tissue composed of sphaerocyte cells and amyloid ornamentation on their basidiospores. Some of the important ectomycorrhizal, edible, poisonous and medicinal species have been rested in genera Lactarius an...
