  double
We obtain a criterion for rational smoothness of an algebraic variety with a torus action, with applications to orbit closures in flag varieties, and to closures of double classes in regular group completions.
      
A Deodhar-type stratification on the double flag variety
      
We describe a partition of the double flag variety G/B+ × G/B- of a complex semisimple algebraic group G analogous to the Deodhar partition on the flag variety G/B+.
      
Also, we discuss possible connections to the positive and cluster geometry of G/B+ × G/B-, which would generalize results of Fomin and Zelevinsky on double Bruhat cells and Marsh and Rietsch on double Schubert cells.

  two
Motivated by the physical concept of special geometry, two mathematical constructions are studied which relate real hypersurfaces to tube domains and complex Lagrangian cones, respectively.
      
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.
      
Recently, there is a renewed interest in wonderful varieties of rank two since they were shown to hold a keystone position in the theory of spherical varieties, see [L], [BP], and [K].
      
We apply this criterion of algebraic integrability to two examples: finite-zone potentials and the elliptic Calogero-Moser system.
      
There are two well known combinatorial tools in the representation theory ofSLn, the semi-standard Young tableaux and the Gelfand-Tsetlin patterns.

  dual
The cohomology algebra of the classifying space of a compact Lie group admits the structure of ann-Hopf algebra, wheren is the order of the Weyl group; the homology with dual structure is also ann-Hopf algebra.
      
In a first step we prove that the Satake compactification of the modular variety of genus 2 and level 3 is the normalization of the dual of the Burkhardt quartic.
      
The second part consists in the normalization of the Burkhardt dual.
      
Finally, we study their reducibility of the action of the Casimirs on the zero-weight spaces of self-dual g-modules and obtain complete classification results for g = sln and g2.
      
This boils down to a Duistermaat-Heckman exact stationary phase calculation, involving a Poisson structure on the dual symmetric space G0/K discovered by Evens and Lu.

Fr?nsdal [Fr1, Fr2] made a penetrating observation that both of them are quasi-Hopf algebras, obtained by twisting the standard quantum affine algebraUq(g).
      
We find closed formulas for the 1-point functions in both cases in terms of Jacobi θ-functions.
      
We characterize irreducible Hermitian symmetric spaces which are not of tube type, both in terms of
      
This partition is a refinement of the stratification into orbits both for B+ × B- and for the diagonal action of G, just as Deodhar's partition refines the orbits of B+ and B-.
      
Hardy spaces of analytic functions are studied both on strongly pseudoconvex domains in ?n and on domains of finite type in ?2.

The overall reaction of chlorination of O,O-diethyldithiophosphoric acid,giving O,O-diethyl-thiophosphoryl chloride and sulphur monochloride,is found to consist of following successivesteps:One of the reaction intermediates,bis-(diethylthionophosphate) disulphide,has been isolatedand identified,and another intermediate,the diethyhhionophosphate sulphur chloride,whichis too unstable to be isolated,has been identified indirecdy through the following reaction:(?)A crystalline solid appearing in the course of the chlorination is found to be bis-(diethyl-thionophosphate) trisulphide,which in turn,upon further chlorination,is converted similarlyinto O,O-diethylthiophosphoryl chloride and sulphur monochloride.The present study indicatesthat the formation of the trisulphide depends presumably upon the reaction temperature.In view of the fact that the diethylthionophosphate sulphur chloride decomposes uponheating into free sulphur and O,O-diethylthiophosphoryl chloride,the reaction is exploited byauthors in the hope of simplifying the process in the manufacturing of O,O-diethylthiophosphorylchloride.The result has shown that the reaction cannot be controlled conveniently.With sul-phur monochloride as chlorinating agent,however,the reaction proceeds satisfactorily.

Methylchlorosilanes were successfully chlorinated with sulfuryl chloride, when azo-bis-isobuty-ronitrile was used as free radical initiator, giving the corresponding monochlorinated products. The rate of reaction decreased when more Si-Cl bonds were present in the silane to be chlorinated. Increasing the quantity of the initiator increased the rate of reaction.Trimethylchloromethylsilane was also chlorinated with sulfuryl chloride and benzoyl peroxide, both dichloromethyltrimethylsilane and di(chloromethyl)dimethylsilane...
