Coarsely Invariant Hilbert Spaces over Infinite Connected Graphs

We study in this paper a Hilbert space HV associated with the coarse geometry of an infinite connected graph X(V,E) with vertex set V and edge set E. We show that X( V, E) is uniformly expanding if and only if l2( V) can be continuously included in HV as a closed subspace, and that the inner product structure of HV is topologically invariant under uniform coarsening of the graph. We also discuss the functorial properties of these Hilbert spaces.

A New Shaping Model for Green Ceramic Balls

The shaping quality of green ceramic balls is directly related to the efficiency and cost of later machining for the ceramic balls. Until now the shaping for green ceramic balls is still conducted by handwork. In this paper, a new shaping model for green ceramic balls was designed. In the new model, two grinding wheels with the same generator line as circular arc are mounted on symmetry, and their axes are parallel. The green ball can be put in the enveloping space formed by the two grinding wheels. The rad...
