Bounded and open: $\emptyset$, $(0,1)$. To check that these examples have the correct properties, go through the definitions of boundedness, openness, and closedness carefully for each set. Applying definitions to examples is a great way to build intuition.

WebAd question 1): Yes, all open star-shaped subsets of $\mathbb{R}^n$ are diffeomorphic to $\mathbb{R}^n$. This is surprisingly little-known and there is a proof due to Stefan Born.

A set S of real numbers is called bounded from above if there exists some real number k (not necessarily in S) such that k ≥ s for all s in S. The number k is called an upper bound of S. The terms bounded from below and lower bound are similarly defined. A set S is bounded if it has both upper and lower bounds. Therefore, a set of r… WebLet s be an upper bound for A. Then for some ϵ, there is a ball B ϵ ( s) around s contained in A, since A is open. But in particular, s + ϵ 2 lies in A, contradicting that s is an upper …
