 components
 A varietyQ??19 is explicitely constructed as the union of 22 disjoint irreducible components which are either points or open subsets of linear spaces. Semi-invariants of quivers can be constructed by taking admissible partial polarizations of the determinant of matrices containing sums of matrix components of the representation and the identity matrix as blocks. Secon, we are interested in dominant polynomial mapsF:?n→?n-1 whose connected components of their generic fibers are contractible. A fundamental question is how the irreducible components are embedded in the tensor product. We give a characterization and a combinatorial description of representations with small Cartan components. 更多
 component
 Finally the cubic surfaces of each component ofQ are studied in details by determining their stabilizers, their rational representations and whether they can be expressed as the determinant of a 3×3 matrix of linear forms. LetD be a Hermitian symmetric space of tube type,S its Shilov boundary andG the neutral component of the group of bi-holomorphic diffeomorphisms ofD. This underlying group H1(X, T \bar{X}) can be described as a generalized Prym variety, whose connected component is either an abelian variety or a degenerate abelian variety. A special component of the tensor product is the so-called Cartan component Vλ+μ which is the component with maximal highest weight. Consider a non-connected algebraic group G = G ? Γ with semisimple identity component G and a subgroup of its diagram automorphisms Γ. 更多
 composition
 We study the composition of the functor from the category of modules over the Lie algebra $\mathfrak{gl}_m$ to the category of modules over the degenerate affine Hecke algebra of GLN introduced by I. We also establish a connection between the composition of the functors, and the "centralizer construction" of the Yangian ${\rm Y}(\mathfrak{gl}_n)$ discovered by G. We also determine all the composition factors of the symmetric tensors of the natural osp(2|2n)-module. For Fourier-bandlimited symbols, we derive the expected formulae for composition and commutators and construct an orthonormal basis of common approximate eigenvectors that could be used to study spectral theory.

Secon, we are interested in dominant polynomial mapsF:?n→?n-1 whose connected components of their generic fibers are contractible. Generic stability and existence of essential components of the solution set for the system of generalized vector equilibrium pro 3-Ene-1, 5-diynes are important components of many enediyne antitumor agents and luminescent materials. One of the most critical hardware components of a ground-penetrating radar (GPR) is the antenna system. 更多
