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 $n - 1$

Classification of simple closed curves on the punctured torus
I am looking for a reference for the following fact:
Consider the fundamental group of the once punctured torus $\pi_1(T^\ast)\cong F_2$ generated by elements $a$ and $b$. An oriented curve $[\alpha]$ up to free homotopy is simple iff $[\alpha]$, as a conjugacy class of $\pi_1(T^\ast)$, is of the following... -

Is partitioning a graph into matchings of size $m$ polynomially solvable?
Holyer (1981) proved that for each fixed $m\ge 3$, it is NP-complete to determine whether an arbitrary graph can be edge-partitioned into subgraphs isomorphic to the complete graph $k_m$. Dor and Tarsi (1992) extended the result to subgraphs isomorphic...

A relational-power hierarchy and its relation to Jensen's hierarchy and $L$
Fix a coding of ordered pairs, say Quine--Rosser ordered pairs, and write the ordered pair of $a$ and $b$ as
$$\langle a,b\rangle.$$
For a set $X$, I want to define a "relational power set" of $X$, denoted
