... In this article we formulate and prove the analogue of this theorem for SU (N ) symmetric extended Hubbard–Heisenberg chains with pair-hopping term. Recently, the spin and fermionic chains with such symmetry have been ... Lihat dokumen lengkap

... The mechanical analogue system of field theoretical models with N scalar fields has N degrees of freedom and the system of N motion ODE’s is rarely integrable. One may analytically find the solitary waves in field ... Lihat dokumen lengkap

... It is known that the notion of spectral distance is related naturally to the notion of spectral triple. For general reviews on noncommutative spectral geometry and related notion of spectral distance, see e.g. [1, 3]. So ... Lihat dokumen lengkap

... In this paper we present new results for two higher genus trigonal curves. The aim was to give further examples of results to build towards a general trigonal case and to investigate the question of whether it is the ... Lihat dokumen lengkap

... Roughly speaking, nonholonomic systems are mechanical systems with velocities constrained to lie in a given non-integrable distribution. Following the fundamental paper of Koiller [16] there has been a lot of interest in ... Lihat dokumen lengkap

... Here we shall examine exact solutions to noncommutative gravity, and show that they can give rise to effects which are linear in the noncommutative scale when additional gauge fields are present in the theory. Such ... Lihat dokumen lengkap

... Manin and Radul in 1985 [10], introduced a new system of equations for an infinite set of even and odd functions, depending on an even-odd pair of space variables and even-odd times. This system of equations now ... Lihat dokumen lengkap

... where we assume r, s ∈ N , r + s odd, and ω 1 , ω 2 > 0. This type of Hamiltonians, which represent a natural generalization of the quantum Henon–Heiles model, has been studied also in [11, 12]. We will analyze ... Lihat dokumen lengkap

... Theory of the so-called PT -symmetric Hamiltonians has been a very active research area in recent years [1, 2, 3, 5, 7, 8, 9, 10, 13]. While they are not self-adjoint in general, many PT - symmetric Hamiltonians ... Lihat dokumen lengkap
