Symplectic reflection algebras in positive characteristic
Kenneth A. Brown, Kanokporn Changtong
Basic properties of symplectic reflection algebras over an algebraically closed field k of positive characteristic are laid out. These algebras are always finite modules over their…
Primeness, semiprimeness and localisation in Iwasawa algebras
Konstantin Ardakov, Kenneth A. Brown
Necessary and sufficient conditions are given for the completed group algebras of a compact p-adic analytic group with coefficient ring the p-adic integers or the field of p elemen…
Rational Cherednik algebras and Hilbert schemes
I. Gordon, J. T. Stafford
Let H_c be the rational Cherednik algebra of type A_{n-1} with spherical subalgebra U_c = eH_ce. Then U_c is filtered by order of differential operators, with associated graded rin…
Unruffled extensions and flatness over central subalgebras
Kenneth A. Brown
A condition on an affine central subalgebra of a noetherian algebra of finite Gelfand-Kirillov dimension, which we call here \emph{unruffledness}, is shown to be equivalent…
An Objective Representation of the Gaussian Integers
Marcelo Fiore, Tom Leinster
A rig is a riNg without Negatives. We analyse the free rig on a generator x subject to the equivalence x = 1 + x + x^2, showing that in it the non-constant polynomials form a ring.…
