A quantum Capelli identity is given on the multiparameter quantum general linear group based on the (p ij , u)-condition. The multiparameter quantum Pfaffan of the (p ij , u)-quantum group is also introduced and the transformation under the congruent action is given. Generalization to the multiparameter hyper-Pfaffan and relationship with the quantum minors are also investigated. 相似文献

We prove that if a semiprime ringR possesses a derivation which is integral over its extended centroidC and whose constants satisfy a polynomial identity, thenR itself is a PI-ring. This answers affirmatively a problem raised by M. Smith in 1975 and recently again by Bergen and Grzeszczuk

Let be the group algebra of a group over a field , and let be its group of units. A conjecture by Brian Hartley asserts that if is a torsion group and satisfies a group identity, then satisfies a polynomial identity. This was verified earlier in case is an infinite field. Here we modify the original proof so that it handles fields of all sizes.

We study group algebras FG for which the symmetric units under the natural involution: g*=g−1 satisfy a group identity. For infinite fields F of characteristic ≠2, a classification of torsion groups G whose symmetric units U+(FG) satisfy a group identity was given in [3] by Giambruno-Sehgal-Valenti. We extend this work to non torsion groups.

We develop a necessary and sufficient condition for the Bedrosian identity in terms of the boundary values of functions in
the Hardy spaces. This condition allows us to construct a family of functions such that each of which has non-negative instantaneous
frequency and is the product of two functions satisfying the Bedrosian identity. We then provide an efficient way to construct
orthogonal bases of L
2(ℝ) directly from this family. Moreover, the linear span of the constructed basis is norm dense in L
p
(ℝ), 1 < p < ∞. Finally, a concrete example of the constructed basis is presented. 相似文献

We prove that a residually finite group G satisfying an identity \(w\equiv 1\) and generated by a commutator closed set X of bounded left Engel elements is locally nilpotent. We also extend such a result to locally graded groups, provided that X is a normal set. As an immediate consequence, we obtain that a locally graded group satisfying an identity, all of whose elements are bounded left Engel, is locally nilpotent. 相似文献

For a real reductive dual pair the Capelli identities define a homomorphism from the center of the universal enveloping algebra of the larger group to the center of the universal enveloping algebra of the smaller group. In terms of the Harish-Chandra isomorphism, this map involves a -shift. We view a dual pair as a Lie supergroup and offer a construction of the homomorphism based solely on the Harish-Chandra's radial component maps. Thus we provide a geometric interpretation of the -shift.

In this paper are defined cohomology-like groups that classify loop extensions satisfying a given identity in three variables for association identities and in two variables for the case of commutativity. It is considered a large amount of identities. These groups generalize those defined in Nishigori [3] and of Kenneth and Leedham-Green [2]. It is computed the number of metacyclic extensions for trivial action of the quotient on the kernel in one particular case for left Bol loops and in general for commutative loops. 相似文献
