... divisor of p n − 1. If (v − 1)/q ≡ 0 (mod 12), then there is no bowtie decomposition of K v which is invariant with respect to G. Proof. We identify the vertices of the complete graph with the elements ... 1. The coset G − ρ consists of the permutations on Z v of the form x → −x + i + 1. Each element o f G − ρ is a reflection about the axis passing through th...

... 13, 1994. Abstract. Bounds on the number of simple zeros of the derivatives of a function are used to give bounds on the number of distinct zeros of the function. The Riemann ξ-function is defined ... generically, the left side of (7) equals N (j) s (T ). In other words, the zeros of the derivatives of a generic function are all simple, except for those which ar...
