Shape Operator of Slant Submanifolds in Kenmotsu Space Forms

Hypersurfaces of a Sasakian space form with recurrent shape operator

Let $(M^{2n},g)$ be a real hypersurface with recurrent shapeoperator and tangent to the structure vector field $xi$ of the Sasakian space form$widetilde{M}(c)$. We show that if the shape operator $A$ of $M$ isrecurrent then it is parallel. Moreover, we show that $M$is locally a product of two constant $phi-$sectional curvaturespaces.

Perceived three-dimensional shape toggles perceived glow

Most surfaces reflect light from external sources, but others emit light: they glow. Glowing surfaces are often a sign of an important feature of the environment, such as a heat source or a bioluminescent life form, but we know little about how the human visual system identifies them. Previous work has shown that luminance and luminance gradients are important in glow perception [1,2]. While a ...

Inconsistency of perceived 3D shape

Internal consistency of local depth, slant, and curvature judgments was studied by asking participants to match two 3D surfaces rendered by different mixtures of 3D cues (velocity, texture, and shading). We found that perceptual judgments were not consistent with each other, with cue-specific distortions. Adding multiple cues did not eliminate the inconsistencies of the judgments. These results...

The Shape of Space

Typically a search problem is posed as an optimisation task in which a cost, or fitness, function must be maximised or minimised, subject to various parameter constraints. This paper discusses “the shape of space”, in terms of search algorithms. We point out that it is the combination of representation and traversal operators that define an algorithm's view of a given search problem, and hence ...
