A relativistic quantum field theory is presented for finite density problems based on the principle of locality. It is shown that, in addition to the convention

We calculate the corrections of extended technicolor (ETC) interactions to the asymmetry parameter ALR and the polarized parameters pLt, PtR of the process e+ e
Two kinds of spin-depcndcnt scattering effects (magnetic-iinpurity and spin-orbit scatterings) axe investi-gated theoretically in a quasi-two-dimensional (quasi
The effects of solution transformations to the six- and eight-vertex systems are discussed.Tthere are fourkinds of effects,the Hamiltonian of the system is inva
A new mechanism for mass generation of gauge field is discussed in this paper. By introducing two sets of gauge fields and making the variations of these two se
By means of the heat conduction equation and the standard truncated Painlevé expansion, the (1+1) dimensional Kupershmidt equation is solved. Some signific
