Equivariant quantum cohomology of homogeneous spaces
We prove a Chevalley formula for the equivariant quantum multiplication of
two Schubert classes in the homogeneous variety X=G/P. As in the case when X is
a Grassmannian, studied by the author in a previous paper, this formula implies
an effective algorithm to compute the structure constants of the equivariant
quantum cohomology algebra of X.Comment: 21 page
Discovering and managing creativity in product development
Creativity is a result of brain activity which differentiates individuals from each other and could ensure an important competitive advantage for a person or for a company. For very innovative branches - like soft ware industry, computer industry, or for automotive industry - creativity is the key of business success. The students should learn that every person can develop basic creative activities, but professional creativity should be trained and it could be enhanced over the level of employees' natural possibilities. They should learn that neurological research still does not offer a scientific basis for understanding creativity but thousand years of creative behavior observations offer some guidelines and procedures which could be used successfully in product development.creativity, managing creativity, product development
Chern classes of Schubert cells and varieties
We give explicit formulas for the Chern-Schwartz-MacPherson classes of all
Schubert varieties in the Grassmannian of -planes in a vector space, and
conjecture that these classes are effective. We prove this is the case for
(very) small values of .Comment: 31 pages, several figure
