A fire with global connections

Indonesia has been suffocating under an orange haze for months. By the end of October, half a million people had been treated for respiratory problems caused by the polluted air. Schools had to close and children were evacuated by military vessels in the worst affected areas. At times, the haze even affected northern neighbours Vietnam and Cambodia. The habitual slash-and-burn approach of local...

Global Warming: East-West Connections

Air pollutants that damage human health and agricultural productivity, such as tropospheric ozone and black soot, also affect global climate. Multiple benefits of reducing these pollutants become more compelling as concern about global warming increases. Air pollution is especially harmful in developing countries that are now large emitters of carbon dioxide, providing incentive for developed a...

Canonical Duality Theory: Connections between nonconvex mechanics and global optimization

This paper presents a comprehensive review and some new developments on canonical duality theory for nonconvex systems. Based on a tri-canonical form for quadratic minimization problems, an insightful relation between canonical dual transformations and nonlinear (or extended) Lagrange multiplier methods is presented. Connections between complementary variational principles in nonconvex mechanic...
