Foreign aid workers and Sri Lankans raced to provide basics such as clean drinking water and latrines. “The response of the government has been excellent,” Pole says. “They forgot all the usual bureaucracy and cleaned out their store.” Emergency supplies flowed to all the affected communities, including those in the northeast controlled by the Liberation Tigers of Tamil Eelam (LTTE), the rebels...

We study multiplicity space signatures in tensor products of sl2 and Uq(sl2) representations and theirapplications. We completely classify definite multiplicity spaces for generic tensor products of sl2 Vermamodules. This provides a classification of a family of unitary representations of a basic quantized quivervariety, one of the first such classifications for any quantized qu...

We give an explicit formula for invariant *-products on a wide class of coadjoint orbits. The answer is expressed in terms of the Shapovalov pairing for generalized Verma modules.
