One of the intriguing aspects of K-theory is its connection to the geometry of manifolds, particularly in the context of positive scalar curvature. Recent research has explored various facets of K ...

In Blackbird in Snow, the bird and branches take up positive space in the top half of the frame. The bottom half of the composition is almost entirely negative space. This creates a sense of ...

either in on itself like a ball (“positive” curvature) or out on itself like a saddle (“negative” curvature). In fact, it’s darn nearly flat. Not only that, but even bits of it far off ...

Structures with this kind of negative curvature have a spongy ... "We're able to extend the economics of shapes with a positive curvature to a much more complex set of structures that can be ...
