For motivation, we start by exhibiting the elementary notions at work in the example of sheaves on a topological space. divided into separate screens. In other words, an integer is a prime number if the only integers that divide it an exact number of times, without leaving a remainder, are one and itself. To move data records up in memory to make space to insert further records. This shows that having a way to give a true syntax for talking about higher category theory in a purely syntactic way (i.e., an n n-directed higher type theory for every n n) is an interesting problem, even if it is not yet completely solved for the 1 1-categorical setting, and that an important model for extracting the properties of such a .
