On the Cohen-Macaulay property of multiplicative invariants
Martin Lorenz
We investigate the Cohen-Macaulay property for rings of invariants under multiplicative actions of a finite group . By definition, these are -actions on Laurent polynomial al…
Maximum and comparison principles for convex functions on the Heisenberg group
Cristian E. Gutierrez, Annamaria Montanari
We prove estimates, similar in form to the classical Aleksandrov estimates, for a Monge-Ampere type operator on the Heisenberg group. A notion of normal mapping does not seem to be…
Higher-dimensional Dedekind sums and their bounds arising from the discrete diagonal of the n-cube
Matthias Beck, Sinai Robins, Shelemyahu Zacks
Higher-dimensional Dedekind sums are defined as a generalization of a recent 1-dimensional probability model of Dilcher and Girstmair to a d-dimensional cube. The analysis of the f…
A Remark on "Counting primitive elements in free groups" (by J. Burillo and E. Ventura)
Igor Rivin
We observe that a sharp result on the exponential growth rate of the number of primitive elements exists for the free group on two generators.
Symmetrized Chebyshev Polynomials
Igor Rivin
We define a class of multivariate Laurent polynomials closely related to Chebyshev polynomials, and prove the simple but somewhat surprising (in view of the fact that the signs of…
