چکیده
We construct covariant q-deformed holomorphic structures for all finitely generated relative Hopf modules over the irreducible quantum flag manifolds endowed with their Heckenberger–Kolb calculi. In classical limit, these reduce to of sections homogeneous vector bundles manifolds. For case simple modules, we show that this structure is unique. This generalises earlier work Majid, Khalkhali, Landi, and van Suijlekom line Podleś sphere, subsequent Khalkhali Moatadelro general projective space.

Holomorphic bundles on diagonal Hopf manifolds
Let A ∈ GL(n,C) be a diagonal linear operator, with all eigenvalues satisfying |αi| < 1, and M = (Cn\0)/〈A〉 the corresponding Hopf manifold. We show that any stable holomorphic bundle on M can be lifted to a G̃F equivariant coherent sheaf on C, where G̃F ∼= (C) is a commutative Lie group acting on C and containing A. This is used to show that all stable bundles onM are filtrable, that is, admit a...

The theory of Doi-Hopf modules [7, 10] is generalized to Weak Hopf Algebras [1, 12, 2].
متن کاملOn the Cohomology of Relative Hopf Modules
Let H be a Hopf algebra over a field k, and A an Hcomodule algebra. The categories of comodules and relative Hopf modules are then Grothendieck categories with enough injectives. We study the derived functors of the associated Hom functors, and of the coinvariants functor, and discuss spectral sequences that connect them. We also discuss when the coinvariants functor preserves injectives.
متن کاملQuantum Cohomology of Flag Manifolds
In this paper, we study the (small) quantum cohomology ring of the partial flag manifold. We give proofs of the presentation of the ring and of the quantum Giambelli formula for Schubert varieties. These are known results, but our proofs are more natural and direct than the previous ones. One of our goals is to give evidence of a relationship between universal Schubert polynomials, which give t...
متن کاملDe Rham Complex for Quantized Irreducible Flag Manifolds
It is shown that quantized irreducible flag manifolds possess a canonical q-analogue of the de Rham complex. Generalizing the well known situation for the standard Podleś’ quantum sphere this analogue is obtained as the universal differential calculus of a distinguished first order differential calculus. The corresponding differential d can be written as a sum of differentials ∂ and ∂. The univ...
