Howe dual pair
A reductive dual pair is called reducible if it can be obtained in this fashion from smaller groups, and irreducible otherwise. A reducible pair can be decomposed into a direct product of irreducible ones, and for many purposes, it is enough to restrict one's attention to the irreducible case. Meer weergeven In the mathematical field of representation theory, a reductive dual pair is a pair of subgroups (G, G′) of the isometry group Sp(W) of a symplectic vector space W, such that G is the centralizer of G′ in Sp(W) and vice … Meer weergeven The notion of a reductive dual pair makes sense over any field F, which we assume to be fixed throughout. Thus W is a symplectic vector space over F. If W1 and W2 are two symplectic vector spaces and (G1, G′1), (G2, G′2) are two reductive … Meer weergeven • The full symplectic group G = Sp(W) and the two-element group G′, the center of Sp(W), form a reductive dual pair. The double centralizer property is clear from the way these groups were defined: the centralizer of the group G in G is its center, and … Meer weergeven • Howe correspondence between representations of elements of a reductive dual pair. • Heisenberg group Meer weergeven WebTHEOREM D.

WebChapter II]). In this instance, Howe’s treatment of dual pairs in certain Lie algebras gives rise to a classi cation of the dual pairs in Sp(2n;C). However, it is not, in general, the case that the dual pairs in an algebraic group Gcan be understood by looking at the dual pairs in the Lie algebra associated to G. WebThe invariance of this system is reduced to the unitary group. In this paper we show that this choice of equations is fully justified. Indeed, constructing the Howe dual for the action of the unitary group on the space of all spinor valued polynomials, the generators of the resulting Lie superalgebra reveal the natural set of equations to be ...
