Commuting charges and symmetric spaces [PDF]

, 2000
Every classical sigma-model with target space a compact symmetric space $G/H$ (with $G$ classical) is shown to possess infinitely many local, commuting, conserved charges which can be written in closed form.

Role of snow-albedo feedback in higher elevation warming over the Himalayas, Tibetan Plateau and Central Asia

Environmental Research Letters, 2014
Recent literature has shown that surface air temperature (SAT) in many high elevation regions, including the Tibetan Plateau (TP) has been increasing at a faster rate than at their lower elevation counterparts.

Amplified warming projections for high altitude regions of the northern hemisphere mid-latitudes from CMIP5 models

Environmental Research Letters, 2013
We use output from global climate models available from the Coupled Model Intercomparison Project Phase 5 (CMIP5) for three different greenhouse gas emission scenarios to investigate whether the projected warming in mountains by the end of the 21st ...
