چکیده
Abstract We consider the third quantization in quantum cosmology of a minisuperspace extended by Eisenhart–Duval lift. study based on both Klein–Gordon type and Dirac-type equations minisuperspace. Spontaneous creation ‘Universes’ is investigated upon simple model. find that wave function reveals number density universes expressed Fermi–Dirac distribution. also calculate entanglement entropy multi-universe system.

Scalar and Spinor Two-Point Functions in Einstein Universe
Two-point functions for scalar and spinor fields are investigated in Einstein universe (R ⊗ S). Equations for massive scalar and spinor two-point functions are solved and the explicit expressions for the two-point functions are given. The simpler expressions for massless cases are obtained both for the scalar and spinor cases. e-mail : [email protected] e-mail : ishikawa@t...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
