Geometric topology | Topological spaces
In geometric topology, the dogbone space, constructed by R. H. Bing, is a quotient space of three-dimensional Euclidean space such that all inverse images of points are points or , yet it is not homeomorphic to . The name "dogbone space" refers to a fanciful resemblance between some of the diagrams of genus 2 surfaces in R. H. Bing's paper and a dog bone. showed that the product of the dogbone space with is homeomorphic to . Although the dogbone space is not a manifold, it is a and a . (Wikipedia).
Complex Analysis: Dogbone Contour Generalisation
Today, we come up with a very nice generalisation for an integral using the dogbone contour from complex analysis. Dogbone contour example: https://www.youtube.com/watch?v=UDIKojCQ94U&t=2s Residue at Infinity: https://www.youtube.com/watch?v=n3bD3MW6Hvk
