WebFeb 23, 2024 · An affine space morphism is a separated, smooth morphism whose geometric fibers are affine spaces. Definition 2. A morphism of schemes is a étale cohomological equivalence if the pullback maps on étale cohomology are isomorphisms. The morphism is a universal étale cohomological equivalence if every base change of … WebMay 15, 2024 · For fibrous materials such as nonwoven fabrics, paper and paperboards, inter-fiber bonds play a critical role by holding fibers, thus providing internal cohesion.Being a physical phenomenon, inter-fiber bonds occur at every fiber crossing and can be also geometrically detected. In relation to the idea, a statistical geometrical model was …
