释义 |
In mathematics, a G-measure is a measure that can be represented as the weak-∗ limit of a sequence of measurable functions . A classic example is the Riesz product where . The weak-∗ limit of this product is a measure on the circle , in the sense that for : where represents Haar measure. HistoryIt was Keane[1] who first showed that Riesz products can be regarded as strong mixing invariant measure under the shift operator . These were later generalized by Brown and Dooley [2] to Riesz products of the form where .
