A countably compact space is a topological space in which every countable open cover has a finite subcover. Prove that a second countable space is countably compact $\Leftrightarrow$ it is compact.
Let $Y$ be a subspace of a topological space $X$. If $Z$ is a non-empty subset of $Y$, show that $Z$ is compact as a subspace of $Y \Leftrightarrow$ it is compact as a subspace of $X$.
Let $X$ be a topological space. If $\left{X_i\right}$ is a non-empty finite class of compact subspaces of $X$, show that $\cup_i X_i$ is also a compact subspace of $X$. If $\left{X_j\right}$ is a non-empty class of compact subspaces of $X$ each of which is closed, and if $\bigcap_j X_j$ is non-empty, show that $\cap_j X_j$ is also a compact subspace of $X$.
Let $X$ be a compact space. We know by Theorem A that every closed subspace of $X$ is compact. By considering Example 16-3, show that a compact subspace of $X$ need not be closed.
Textbooks
• An Introduction to Stochastic Modeling, Fourth Edition by Pinsky and Karlin (freely
available through the university library here)
• Essentials of Stochastic Processes, Third Edition by Durrett (freely available through
the university library here)
To reiterate, the textbooks are freely available through the university library. Note that
you must be connected to the university Wi-Fi or VPN to access the ebooks from the library
links. Furthermore, the library links take some time to populate, so do not be alarmed if
the webpage looks bare for a few seconds.
