Generalizations of Bertrand's Postulate to Sums of Any Number of Primes
Joel E. Cohen
In 1845, Bertrand conjectured that twice any prime strictly exceeds the next prime. Tchebichef proved Bertrand's postulate in 1850. In 1934, Ishikawa proved a stronger result: the…
Taylor's Law for some infinitely divisible probabbility distributions from population models
Joel E. Cohen, Thierry E Huillet
In a family of random variables, Taylor's law or Taylor's power law offluctuation scaling is a variance function that gives the variance of a random variable (rv) wit…
Nonconcavity of the Spectral Radius in Levinger's Theorem
Lee Altenberg, Joel E. Cohen
Let be a nonnegative irreducible square matrix and let be its spectral radius and Perron-Frobenius eigenvalue. Levinger asserted and sever…
Sample and population exponents of generalized Taylor's law
Andrea Giometto, Marco Formentin, Andrea Rinaldo +2
Taylor's law (TL) states that the variance of a non-negative random variable is a power function of its mean , i.e. . The ubiquitous empirical verification of TL, t…
