Centauros and/or Chirons as evaporating mini black holes
Theodore N. Tomaras
It is argued that the signals expected from the evaporation of mini black holes - predicted in TeV-scale gravity models with large extra dimensions and possibly produced in ultra h…
Non-stationary variability in AGN: the case of 3C 390.3
M. Gliozzi, I. E. Papadakis, R. M. Sambruna +1
We use data from a two-year intensive RXTE monitoring campaign of the broad-line radio galaxy 3C 390.3 to investigate its stationarity. In order to exploit the potential informatio…
Lucas sequences whose 8th term is a square
Andrew Bremner, Nikos Tzanakis
Let P and Q be non-zero integers. The Lucas sequence U_n(P,Q), n=0,1,2,... is defined by U_0=0, U_1=1, U_n= P U_{n-1}-Q U_{n-2} for n>1. For each positive integer n<8 we describe a…
Tiles with no spectra
Mihail N. Kolountzakis, Mate Matolcsi
We exhibit a subset of a finite Abelian group, which tiles the group by translation, and such that its tiling complements do not have a common spectrum (orthogonal basis for their…
Lower bound for the maximal number of facets of a 0/1 polytope
D. Gatzouras, A. Giannopoulos, N. Markoulakis
We show that there exist 0/1 polytopes in R^n with as many as (cn / (log n)^2)^(n/2) facets (or more), where c>0 is an absolute constant.
Lucas sequences whose 12th or 9th term is a square
Andrew Bremner, Nikos Tzanakis
Let P and Q be non-zero relatively prime integers. The Lucas sequence {U_n(P,Q) is defined by U_0=0, U_1=1, U_n = P U_{n-1}-Q U_{n-2} for n>1. The sequence {U_n(1,-1)} is the famil…
