Zero counting for a class of univariate Pfaffian functions
(Academic Press Inc Elsevier Science, 2016-04)
We present a new procedure to count the number of real zeros of a class of univariate Pfaffian functions of order 1. The procedure is based on the construction of Sturm sequences for these functions and relies on an oracle ...
Modelos de sobrevivência induzidos por fragilidade discreta série de potência zero-modificada
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2020-03-13)
Survival models with a frailty term are presented as an extension of Cox's proportional risk model (COX, 1972), in which a random effect, called frailty, is introduced in the risk function in a multiplicative way with the ...
A conjecture about the non-trivial zeroes of the Riemann zeta function

Generalized partition function zeros of 1D spin models and their critical behavior at edge singularities
(Iop Publishing Ltd, 2010-06-25)
Here we study the partition function zeros of the one-dimensional Blume-Emery-Griffiths model close to their edge singularities. The model contains four couplings (H, J, Delta, K) including the magnetic field H and the ...

A lattice gas of prime numbers and the Riemann Hypothesis
(Elsevier Science, 2013-10)
In recent years, there has been some interest in applying ideas and methods taken from Physics in order to approach several challenging mathematical problems, particularly the Riemann Hypothesis. Most of these kinds of ...
Correlation functions in super liouville theory
(1992-12-01)
We calculate three- and four-point functions in super Liouville theory coupled to a super Coulomb gas on world sheets with spherical topology. We first integrate over the zero mode and assume that a parameter takes an ...
