WitrynaThese special collections of sets are called bases of topologies. Exercise 1.1. Let X be a nonempty set, and let B= ffxg: x2Xg. Show that if Tis a topology on Xand B T, then … In mathematics, a base (or basis) for the topology τ of a topological space (X, τ) is a family $${\displaystyle {\mathcal {B}}}$$ of open subsets of X such that every open set of the topology is equal to the union of some sub-family of $${\displaystyle {\mathcal {B}}}$$. For example, the set of all open … Zobacz więcej Given a topological space $${\displaystyle (X,\tau )}$$, a base (or basis ) for the topology $${\displaystyle \tau }$$ (also called a base for $${\displaystyle X}$$ if the topology is understood) is a family For example, … Zobacz więcej • A topology $${\displaystyle \tau _{2}}$$ is finer than a topology $${\displaystyle \tau _{1}}$$ if and only if for each $${\displaystyle x\in X}$$ and each basic open set Zobacz więcej We shall work with notions established in (Engelking 1989, p. 12, pp. 127-128). Fix X a topological space. Here, a network is a family $${\displaystyle {\mathcal {N}}}$$ of sets, for which, for all points x and open neighbourhoods U containing x, there exists B in Zobacz więcej The set Γ of all open intervals in $${\displaystyle \mathbb {R} }$$ forms a basis for the Euclidean topology on $${\displaystyle \mathbb {R} }$$.

The purpose of sleeves is to fix the permanent magnets and protect them from being destroyed by the large centrifugal force. However, the sleeve material characteristics have a great influence on the PMSM, and therewith, most of …
