The test time for buffing the side of the shoe took 16 s, and the side of the shoe was buffed appropriately for gluing.
This reduces the problem of essential surjectivity to a local problem (gluing data lifts canonically).
The construction involves gluing focusing caps to a surface of non-positive curvature.
We describe a single step called a prefix gluing which may need to be repeated several times in the process of removing a prefix problem.
One has to notice that the above gluing is different from the gluing introduced in previous sections.
The different contact types carry different degrees of difficulty, for example, gluing is considered easier than welding.
In order to get a complete invariant, we have to introduce gluing rules.
Gluing copies of a 3-dimensional polyhedron to obtain a closed nonpositively curved (pseudo)manifold.
