Exactly solvable Hermite, Laguerre, and Jacobi type quantum parametric oscillators
(American Institute of Physics, 201612)We introduce exactly solvable quantum parametric oscillators, which are generalizations of the quantum problems related with the classical orthogonal polynomials of Hermite, Laguerre, and Jacobi type, introduced in the ... 
Analytic investigation of a reactionDiffusion brusselator model with the timespace fractional derivative
(De Gruyter, 201404)It is well known that many models in nonlinear science are described by fractional differential equations in which an unknown function appears under the operation of a derivative of fractional order. In this study, we ... 
On pseudo semisimple rings
(World Scientific Publishing, 201303)A necessary and sufficient condition is obtained for a right pseudo semisimple ring to be left pseudo semisimple. It is proved that a right pseudo semisimple ring is an internal exchange ring. It is also proved that a right ... 
Rings over which flat covers of simple modules are projective
(World Scientific Publishing, 201206)Let R be a ring with identity. We prove that, the flat cover of any simple right Rmodule is projective if and only if R is semilocal and J(R) is cotorsion if and only if R is semilocal and any indecomposable flat right ... 
Motion of vortices outside a cylinder
(American Institute of Physics Publishing, 201012)The problem of motion of the vortices around an oscillating cylinder in the presence of a uniform flow is considered. The Hamiltonian for vortex motion for the case with no uniform flow and stationary cylinder is constructed, ... 
Remark on:"Expfunction method for the exact solutions of fifth order KdV equation and modified Burgers equation" [Appl. Math. Comput. (2009) doi:10.1016/j.amc.2009.07.009]
(Elsevier, 201012)By means of the Expfunction method, Inan and Ugurlu [Appl. Math. Comput. (2009) doi:10.1016/j.amc.2009.07.009] reported eight expressions for being solutions to the two equations studied. In fact, all of them can be easily ... 
Nonlinear integral equations for Bernoulli's free boundary value problem in three dimensions
(Elsevier, 201712)In this paper we present a numerical solution method for the Bernoulli free boundary value problem for the Laplace equation in three dimensions. We extend a nonlinear integral equation approach for the free boundary ... 
Cocoatomically supplemented modules
(Springer, 201712)It is shown that if a submodule N of M is cocoatomically supplemented and M/N has no maximal submodule, then M is a cocoatomically supplemented module. If a module M is cocoatomically supplemented, then every finitely ... 
Observation of top quark production in protonnucleus collisions
