Asymptotics of Multivariate Sequences, part I. Smooth points of the singular variety
R. Pemantle, M. C. Wilson
Given a multivariate generating function F, we determine asymptotics for the coefficients. Our approach is to use Cauchy's integral formula near singular points of F, resulting in…
Primitive ideals in Hopf algebra extensions
Mark C. Wilson
Let be a finite-dimensional Hopf algebra. We study the behaviou r of primitive and maximal ideals in certain types of ring extensions determined by . The main focus is on th…
X-inner automorphisms of semi-commutative quantum algebras
Jeffrey Bergen, Mark C. Wilson
Many important quantum algebras such as quantum symplectic space, quantum Euclidean space, quantum matrices, -analogs of the Heisenberg algebra and the quantum Weyl algebra are…
Associative algebras satisfying a semigroup identity
David M. Riley, Mark C. Wilson
Denote by (R,.) the multiplicative semigroup of an associative algebra R over an infinite field, and let (R,*) represent R when viewed as a semigroup via the circle operation x*y=x…
