Variations on a theme of qoscillator
(IOP Publishing, 20150701)We present several ideas in the direction of physical interpretation of q and foscillators as nonlinear oscillators. First we show that an arbitrary onedimensional integrable system in actionangle variables can be ... 
Vector shock soliton and the Hirota bilinear method
(Elsevier, 200510)The Hirota bilinear method is applied to find an exact shock soliton solution of the system reactiondiffusion equations for ncomponent vector order parameter, with the reaction part in form of the third order polynomial, ... 
Vertexdecomposable graphs, codismantlability, cohenmacaulayness, and castelnuovomumford regularity
(Electronic Journal of Combinatorics, 201401)We call a vertex x of a graph G = (V, E) a codominated vertex if NG[y] ⊆ NG[x] for some vertex y ∈ V \{x}, and a graph G is called codismantlable if either it is an edgeless graph or it contains a codominated vertex x such ... 
Vortex images and qelementary functions
(IOP Publishing, 200804)In the present paper, the problem of vortex images in the annular domain between two coaxial cylinders is solved by the qelementary functions. We show that all images are determined completely as poles of the qlogarithmic ... 
Vortex images, qcalculus and entangled coherent states
(IOP Publishing, 2012)The two circles theorem for hydrodynamic flow in annular domain bounded by two concentric circles is derived. Complex potential and velocity of the flow are represented as qperiodic functions and rewritten in terms of the ... 
Weakly distributive modules. Applications to supplement submodules
(Indian Academy of Sciences, 201011)In this paper, we define and study weakly distributive modules as a proper generalization of distributive modules. We prove that, weakly distributive supplemented modules are amply supplemented. In a weakly distributive ... 
Weighted bloch, lipschitz, zygmund, bers, and growth spaces of the ball: Bergman projections and characterizations
(Elsevier, 201102)We determine precise conditions for the boundedness of Bergman projections from Lebesgue classes onto the spaces in the title, which are members of the same oneparameter family of spaces. The projections provide integral ... 
Well posedness conditions for Bimodal Piecewise Affine Systems
(Elsevier, 20150701)This paper considers wellposedness (the existence and uniqueness of the solutions) of Bimodal Piecewise Affine Systems in ℝn. It is assumed that both modes are observable, but only one of the modes is in observable canonical ... 
Wellposedness for nonlinear Schrödinger equations with boundary forces in low dimensions by Strichartz estimates
(Elsevier, 201504)In this paper, we study the wellposedness of solutions for nonlinear Schrödinger equations on one and two dimensional domains with boundary where the boundary is disturbed by an external inhomogeneous type of Dirichlet ... 
When δsemiperfect rings are semiperfect
(TÜBİTAK, 201009)Zhou defined δ semiperfect rings as a proper generalization of semiperfect rings. The purpose of this paper is to discuss relative notions of supplemented modules and to show that the semiperfect rings are precisely the ...
