ADM formulation of generic massless spin-2 gravity

Doğru, Müslüm
We give a review of the article [1], which uses the Dirac constraint analysis and 3 + 1 split of geometrodynamics[2] to create the Hamiltonian formulation of some gravitational actions. We apply the suggested methods to, Born-Infeld extension of New Massive Gravity, (BINMG) theory and find out the constraints and their classifications except for two constraints. The number of degrees of freedom in BINMG depends on the classification of these two constraints. We could not determine the classes of these two constraints but if some conditions, collected in chapter 4, are satisfied then BINMG is ghost-free at the nonlinear level. If these conditions are not satisfied then, BINMG has a third degree of freedom which does not appear at the linearized studies.


Least-squares finite element solution of Euler equations with H-type mesh refinement and coarsening on triangular elements
AKARGUN, Hayri Yigit; Sert, Cüneyt (2014-01-01)
Purpose - The purpose of this paper is to demonstrate successful use of least-squares finite element method (LSFEM) with h-type mesh refinement and coarsening for the solution of two-dimensional, inviscid, compressible flows.
Forced Oscillation of Second-Order Impulsive Differential Equations with Mixed Nonlinearities
ÖZBEKLER, ABDULLAH; Zafer, Ağacık (2011-07-08)
In this paper we give new oscillation criteria for a class of second-order mixed nonlinear impulsive differential equations having fixed moments of impulse actions. The method is based on the existence of a nonprincipal solution of a related second-order linear homogeneous equation.
Noncommutative nonlinear sigma models and integrability
Kürkcüoğlu, Seçkin (American Physical Society (APS), 2008-09-01)
We first review the result that the noncommutative principal chiral model has an infinite tower of conserved currents and discuss the special case of the noncommutative CP1 model in some detail. Next, we focus our attention to a submodel of the CP1 model in the noncommutative spacetime A(theta)(R2+1). By extending a generalized zero-curvature representation to A(theta)(R2+1) we discuss its integrability and construct its infinitely many conserved currents. A supersymmetric principal chiral model with and wi...

The point canonical transformation (PCT) approach is used to solve the Schrodinger equation for an arbitrary dimension D with a power-law position-dependent effective mass (PDEM) distribution function for the pseudoharmonic and modified Kratzer (Mie-type) diatomic molecular potentials. In mapping the transformed exactly solvable D-dimensional (D >= 2) Schrodinger equation with constant mass into the effective mass equation by using a proper transformation, the exact bound state solutions including the energ...
Nonoscillation and oscillation of second-order impulsive differential equations with periodic coefficients
ÖZBEKLER, ABDULLAH; Zafer, Ağacık (2012-03-01)
In this paper, we give a nonoscillation criterion for half-linear equations with periodic coefficients under fixed moments of impulse actions. The method is based on the existence of positive solutions of the related Riccati equation and a recently obtained comparison principle. In the special case when the equation becomes impulsive Hill equation new oscillation criteria are also obtained.
