Q&A for professional mathematicians
-
I hope everyone is doing well. Let $K \subset \mathbb{R}^n$ be a centrally symmetric convex body $(K = -K)$. Denote by $K \mid H$ the orthogonal projection of $K$ onto $H$, where $H$ is an $n - 1$

Müntz–Szász Theorem on Countable Compact Sets
The classical Müntz theorem states that a set of monomials $\{1\} \cup \{x^\lambda\}_{\lambda \in \Lambda}$ is complete in $C[0,1]$ if and only if $\sum_{\lambda \in \Lambda} \frac{1}{\lambda} = \infty$. On an interval away from the origin, i.e. $C[a...

Recently, I am reading the paper of Fanghua Lin named "A New Proof of the Caffarelli-Kohn-Nirenberg Theorem".
I have a question regarding the proof of Lemma 2.3, the statement of the lemma and proof the lemma as written in the paper is as follows:
Lemma 2.3 : Let $(v,P)$ be a weak solution of (1.1) - (1.2) in $Q_1 = (-1,0)\times B_1$ with $v \in L^\infty(-1,0; L^2_{\sigma}(B_1)) \cap L^2(0,T; H^1_{0,\sigma}(B_1))$. Then $P \in L^{5/3}(-1,0; L^{15/14}(B_1))$.... -

Maximising minimum pairwise distance for points on the boundary of a convex poly...
General question: To place n points on the boundary of a given m-vertex convex polygonal region, maximising the minimum pairwise Euclidean distance between the points. The distance is to be measured over the polygonal region.
Can one form an algorithm that is polynomial in both m and n?...
