Geometric property (T) was defined by Willett and Yu, first for sequences of graphs later more general discrete spaces. Increasing with geometric are expanders, they examples coarse spaces which the maximal Baum-Connes assembly map fails to be surjective. Here, we give a broader definition bounded geometry spaces, includes non-discrete We define generalisation this class show that it is invaria...

Human figures have been animated using a variety of geometric models including stick figures, polygonal models, and NURBS-based models with muscles, flexible skin, or clothing. This paper reports on experimental results indicating that a viewer’s perception of motion characteristics is affected by the geometric model used for rendering. Subjects were shown a series of paired motion sequences an...

A geometric 3-configuration is a collection of points and straight lines, typically in the Euclidean plane, in which every point has 3 lines passing through it and every line has 3 points lying on it; that is, it is an (n3) configuration for some number n of points and lines. We will say that such configuration is symmetric if there are nontrivial isometries of the plane that map the configurat...

Complimentary geometric and non-geometric consistent reductions of IIB supergravity are studied. The geometric reductions on the identified group manifold X = G/Γ are found to have a gauge symmetry with Lie algebroid structure, generalising that found in similar reductions of the Bosonic string theory and eleven-dimensional supergravity. Examples of such compactifications are considered and the...
