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 $n - 1$

Values of cyclotomic polynomials mod p
Let $p,q$ be two distinct odd primes and, as usual, let $\Phi_{p}(x)$ the $p$-th cyclotomic polynomial. The prime divisors of this polynomial are, up to one exception, exactly those $1 \mod p$. In principle, there should be no similar restriction $\mod...
