The Cauchy problem for the Klein-Gordon equation under the quartic potential in the de Sitter spacetime
Makoto Nakamura
The Cauchy problem for the Klein-Gordon equation under the quartic potential is considered in the de Sitter spacetime. The existence of the global solution is shown based on the me…
The Cauchy problem for a semilinear ordinary differential equation in the homogeneous and isotropic spacetime
Makoto Nakamura
A semilinear ordinary differential equation is derived from a semilinear Schrödinger equation in the homogeneous and isotropic spacetime by the Ehrenfest theorem. The Cauchy proble…
On the numerical experiments of the Cauchy problem for semi-linear Klein-Gordon equations in the de Sitter spacetime
Takuya Tsuchiya, Makoto Nakamura
The computational analysis of the Cauchy problem for semi-linear Klein-Gordon equations in the de Sitter spacetime is considered. Several simulations are performed to show the time…
On the derivation of several second order partial differential equations from a generalization of the Einstein equation
Makoto Nakamura
A generalization of the Einstein equation is considered for complex line elements. Several second order semilinear partial differential equations are derived from it as semilinear…
On the nonrelativistic limit of a semilinear field equation in a uniform and isotropic space
Makoto Nakamura
The nonrelativistic limit of a semilinear field equation is considered in a uniform and isotropic space.The scale-function of the space is constructed based on the Einstein equatio…
Improving the Description of Nonmagnetic and Magnetic Molecular Crystals via the van der Waals Density Functional
Masao Obata, Makoto Nakamura, Ikutaro Hamada +1
We have derived and implemented a stress tensor formulation for the van derWaals density functional (vdW-DF) with spin-polarization-dependent gradient correction (GC) recently prop…
