Given a sequence of points in a topological space \(X\), define
\[\textit{convergence to the point } x\in X\]
Given two topologies \(\mathcal{T}_1,\mathcal{T}_2\), define \[\textit{coarser/finer}\]
Give a definition of a topology on a set \(X\) in terms of open sets. Define \(\textit{topological space}\)
