In the Grothendieck cohomology of a flag variety G/H there are two canonical additive bases, namely, the Demazure basis [D] and the Grothendieck basis [KK]. We present explicit formulae that reduce the multiplication of these basis elements to the Cartan numbers of G.

amide-iminol tautomerism was studied for ionized oxamic acid (oa+•) in the gas phase using thedft method with the ub3lyp functional and various basis sets {6-31++g(d,p), 6-311+g(d,p), and augcc-pvdz}. among twenty tautomers-rotamers possible for oa+•, eleven isomers were found to bethermodynamically stable. similarly as for the neutral molecule, ionization (oa → oa+• + e) favors theamidization ...

group dynamic assessment (g-da) grounded in vygotsky’s socio-cultural theory (sct) is believed to have the potential to provide a context for capturing a group of learners’ zone of proximal development (zpd) (poehner & lantolf, 2010; shabani, 2010). the present study aims at testing the applicability of g-da in identifying the mediational strategies offered by a mediator during his g-da int...
