我们给出了一个统计流形能够通过余维数为2的非退化中心仿射浸入来实现的一个充分必要条件。我们还表明,如果一个统计流形如上述那样被实现,那么其对偶统计流形也是如此。此外,我们利用一种几何方法在一个单连通的共形射影平坦统计流形上构造了一个典范对比函数。
We give a necessary and sufficient condition for a statistical manifold to be realized by a nondegenerate centroaffine immersion of codimension two. We also show that if a statistical manifold is realized as above, then so is the dual statistical manifold Moreover, we construct a canonical contrast function on a simply connected conformallyprojectively flat statistical manifold, using a geometric method.
