由随机向量的次线性期望生成的凸体

Convex bodies generated by sublinear expectations of random vectors

Ilya Molchanov, Riccardo Turin

摘要:

我们发现,许多著名的凸几何变换(特别是,质心体,凸浮体,和乌拉姆浮体)的一般建设的特殊情况下,依赖于应用次线性期望随机向量在欧几里得空间。我们确定这样的凸体的对偶表示,并描述了一个建设,作为所有这样定义的凸体的积木。

英文摘要:

We show that many well-known transforms in convex geometry (in particular, centroid body, convex floating body, and Ulam floating body) are special instances of a general construction, relying on applying sublinear expectations to random vectors in Euclidean space. We identify the dual representation of such convex bodies and describe a construction that serves as a building block for all so defined convex bodies.
