The carbon cost of an educated future: A consumer lifestyle approach

Demographic and economic growth will account for most of the anticipated growth in greenhouse gas (GHG) emissions in the next century. Education is associated with development, and the world population in the near future is likely to be significantly better educated than today. Previous studies of household energy demand and associated emissions have not directly considered the consequences of a more educated population. In this study, I estimate the energy intensity of consumption dollars and the total impact of households according to their demographic characteristics, with particular attention to differences in spending habits by education and the environmental consequences. I find that education results in fewer emissions per household, holding other household characteristics constant. Each year of education is associated with an average effect in CO2-equivalent (CO2e) emission of -466kg/yr. After controlling for household characteristics, the effect of a year of education is -163.1kg per year. Educated households spend less on home energy and transportation by car, two of the most important sources of household level atmospheric GHG production. They spend relatively more on investment goods, public transport, and other activities which have a low environmental footprint

Bruhat Order in the Full Symmetric sln\mathfrak{sl}_n Toda Lattice on Partial Flag Space

In our previous paper [Comm. Math. Phys. 330 (2014), 367-399] we described the asymptotic behaviour of trajectories of the full symmetric $\mathfrak{sl}_n$ Toda lattice in the case of distinct eigenvalues of the Lax matrix. It turned out that it is completely determined by the Bruhat order on the permutation group. In the present paper we extend this result to the case when some eigenvalues of the Lax matrix coincide. In that case the trajectories are described in terms of the projection to a partial flag space where the induced dynamical system verifies the same properties as before: we show that when $t\to\pm\infty$ the trajectories of the induced dynamical system converge to a finite set of points in the partial flag space indexed by the Schubert cells so that any two points of this set are connected by a trajectory if and only if the corresponding cells are adjacent. This relation can be explained in terms of the Bruhat order on multiset permutations
