Special representations of Weyl groups: A positivity property

The special representations of a Weyl group W were introduced by the author in 1978. In this paper we show that the special representations of W, when viewed as representations of the corresponding J-ring, are characterized by a positivity property. Keywords: Weyl group; Perron line; Special represe...
