THE HIGHER DIMENSIONAL WHEELER-DEWITT EQUATION AND WAVE FUNCTION OF THE UNIVERSE
Öz
The higher dimensional Arnowitt-Deser-Misner (ADM) formalism is briefly explained. The
higher dimensional Wheeler-DeWitt equation
is obtained for the ten dimensional effective string theory ground state
manifold which has the M4 × C6
form, where M4 denotes the actual 4-dimensional spacetime and C6 denotes the 6-dimensional compact internal
space. The M4 spacetime manifold is the four dimensional sphere in
the Euclidean region or in the quantum gravity region, whereas, the four
dimensional hypersphere in the Lorentzian region or in the very early universe region.
The C6 space manifold is the
six dimensional Euclidean sphere in every region. The Wheeler-deWitt equation
is solved by using of suitable transformations of the relevant metrics scale
factors and the standart methods of the second quantized field theory methods,
i.e., using of normal ordering rules of the field operators. The solution wave
function of the universe has the exponantial varying character in the Euclidean
region, whereas, the oscillatory character in the Lorentzian region.
Furthermore, the wave function has the harmonic oscillator ground state wave
function form for the small values of the relevant metrics scale factors.
