Group classification of (1+1)-Dimensional Schrödinger Equations with Potentials and Power Nonlinearities
Roman O. Popovych, Nataliya M. Ivanova, Homayoon Eshraghi
We perform the complete group classification in the class of nonlinear Schrödinger equations of the form where is an arbitrary complex-valued pot…
Lie Symmetries of (1+1)-Dimensional Cubic Schrödinger Equation with Potential
Roman O. Popovych, Nataliya M. Ivanova, Homayoon Eshraghi
We perform the complete group classification in the class of cubic Schrödinger equations of the form where is an arbitrary complex-valued potenti…
The constant background bag model of the hadron
Sh. Mamedov
We have constructed the bag model having a central constant color field. The motion of the quark is studied in this bag and the Dirac equation is solved for it. The energy spectrum…
Polarized parton distribution functions in the valon model framework, using QCD fits to Bernstein polynomials
Ali N. Khorramian, A. Mirjalili, S. Atashbar Tehrani
In this paper polarized valon distribution is derived from unpolarized valon distribution. In driving polarized valon distribution some unknown parameters exist which must be deter…
Motion of Colored Particle in a Chromomagnetic Field
Sh. Mamedov
The Dirac equation in a chromomagnetic field is solved for colored particle moving in a limited space volume. Quantized energy levels and the corresponding wave functions are found…
Cohomological dimension of complexes
Mohammad T. Dibaei, Siamak Yassemi
In the derived category of the category of modules over a commutative Noetherian ring , we define, for an ideal $\fa$ of , two different types of cohomological dimensions of…
