Studies on the Antidotes against Organophosphorus Poisoning:Ⅱ.The Effect of 2-Pyridine Aldoxime Methiodide(2-PAM)and 1,1′-Trimethylene Bis(4-Formyl PyridiniumBromide)Dioxime(TMB-4)in the Experimental Therapy of Dipterex and Paraoxon Poisoning
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.
Hardy Spaces on the Plane and Double Fourier Transforms
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.
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.
Design, Synthesis and Growth Inhibition Activity of Bis-Epoxyethyl Derivatives of Stallimycin Modified on the Amidino Moiety
We attempted to formulate quantitative structure-activity relationship modeling of 2,5-bis(1-Aziridinyl) 1,4-benzoquinone (BABQ) compounds according to calculated molecular descriptors.
A series of novel C2-symmetrical chiral bis(oxazoline) and bis(thiazoline) ligands containing noncyclic crown ether type was synthesized.
Synthesis and applications of 3,4-dihydroxy-2,5-bis-(2'-(4'-substituted-oxazolinyl)) furan
Three 3,4-dihydroxy-2,5-bis-(2'-(4'-substituted-oxazolinyl)) furans were synthesized at 90%-94% yields from reaction of 3,4-dihydroxyfuran-2,5-dicar-boxylic acid or its dimethyl ester with chiral β-amino alcohol via a one-step process.
