Based on a 2 × 2 eigenvalue problem, a set of (1 + 1)-dimensional soliton equations are proposed. Moreover, we obtain a finite dimensional Hamilton system with
A high detection efficiency calorimeter which is used to detect γ-rays with energies from 1 MeV up to 10 MeV as well as light charged particles has been propos
The Wigner function for the Dirac oscillator in spinor space is studied in this paper.Firstly,since the Dirac equation is described as a matrix equation in phas
The paper considers the problem of testing for a change point in the parameters of AR(p) models. It is shown that the asymptotically limiting distribution of th
In this paper we explicitly determine automorphism group of filiform Lie algebra Rn to find the indecomposable solvable Lie algebras with filiform Lie algebra R
