  1 - On the construction of symmetric nonnegative matrix with prescribed Ritz values
  A. M. Nazaria E. Afshari
  In this paper for a given prescribed Ritz values that satisfy in the some specialconditions, we find a symmetric nonnegative matrix, such that the given set be its Ritz values.

  2 - On the nonnegative inverse eigenvalue problem of traditional matrices
  A. M. Nazari S. Kamali Maher
  In this paper, at first for a given set of real or complex numbers $\sigma$ with nonnegative summation, we introduce some special conditions that with them there is no nonnegative tridiagonal matrix in which $\sigma$ is its spectrum. In continue we present some conditi أکثر

  In this paper, at first for a given set of real or complex numbers $\sigma$ with nonnegative summation, we introduce some special conditions that with them there is no nonnegative tridiagonal matrix in which $\sigma$ is its spectrum. In continue we present some conditions for existence such nonnegative tridiagonal matrices. تفاصيل المقالة
