JM Hennig, SJ Sierra - International Mathematics Research …, 2017 - academic.oup.com
We explore the (noncommutative) geometry of locally simple representations of the diagonal
locally finite Lie algebras,, and. Let be one of these Lie algebras, and let be the non-zero …

A note on noncommutative Poisson structures
W Crawley-Boevey - arXiv preprint math/0506268, 2005 - arxiv.org
We introduce a new type of noncommutative Poisson structure on associative algebras. It
induces Poisson structures on the moduli spaces classifying semisimple modules. Path …

Noncommutative Images of Commutative Spectra
ES Letzter - Journal of Algebra and Its Applications, 2008 - World Scientific
We initiate a unified, axiomatic study of noncommutative algebras R whose prime spectra
are, in a natural way, finite unions of commutative noetherian spectra. Our results illustrate …

Representations of semisimple Lie algebras in prime characteristic and the noncommutative Springer resolution
R Bezrukavnikov, I Mirković - Annals of Mathematics, 2013 - JSTOR
We prove most of Lusztig's conjectures on the canonical basis in homology of a Springer
fiber. The conjectures predict that this basis controls numerics of representations of the Lie …

Noncommutative smoothness and coadjoint orbits
L Le Bruyn - Journal of Algebra, 2002 - Elsevier
In [math. AG/0010030; Math. Z., to appear] R. Bocklandt and the author proved that certain
quotient varieties of representations of deformed preprojective algebras are coadjoint orbits …

Noncommutative Hamiltonian structures and quantizations on preprojective algebras
H Zhao - arXiv preprint arXiv:2312.17578, 2023 - arxiv.org
Given a noncommutative Hamiltonian space $ A $, we show that the conjecture``{\it
quantization commutes with reduction}''holds on $ A $. We also construct a semi-product …

Path algebras and monomial algebras of finite GK-dimension as noncommutative homogeneous coordinate rings
C Holdaway - arXiv preprint arXiv:1412.4918, 2014 - arxiv.org
This article sets out to understand the categories $\QGr A $ where $ A $ is either a monomial
algebra or a path algebra of finite Gelfand-Kirillov dimension. The principle questions are: 1) …

Universal Lie algebra extensions via commutative structures
AB Yanovski - arXiv preprint math/0108142, 2001 - arxiv.org
We consider some special type extensions of an arbitrary Lie algebra, which we call
universal extensions. We show that these extensions are in one-to-one correspondence with …
