Constraints affecting mode choices by morning car commuters

Transport Policy, 2004
In New Zealand as elsewhere, there is an increasing interest in alleviating congestion on the road transport network to improve economic productivity, reduce pollution, and to use the transport network more effectively. Governments enact various policies to encourage car drivers to change their behaviour, but often find that the full impact is not ...

Commutativity of rings with constraints on commutators

2000
This paper studies commutativity of rings \(R\) satisfying polynomial identities of the form\break \(x^t[x^n,y]y^r=[x,y^m]y^s\) and three similar forms, where \(n,m,r,s,t\) are suitably-chosen nonnegative integers. Whether the theorems are correct as stated is not clear, but for some \((n,m,r,s,t)\) the proofs given do not work.

Commutativity of rings with constraints involving a subset

1993
Let \(R\) be a ring. Denote by \(Z(R)\) the center of \(R\), \(N(R)\) the set of nilpotent elements of \(R\), \(A(R)\) a nonempty subset of \(R\), \(\mathbb{Z}[t]\) the ring of polynomials in \(t\) with coefficients in \(\mathbb{Z}\), the ring of integers. As usual, for every \(x\), \(y\) in \(R\), \([x,y] = xy - yx\).
