The evolution of sub-spaces in the framework of gravity with higher derivatives is studied. Numerical solutions to exact differential equations are found. It is shown that the initial conditions play crucial role in the ...

We discuss the way of solving the hierarchy problem. We show that starting at the Planck scale, the three energy scales - inflationary, electroweak and the cosmological ones can be restored. A mechanism for generating small ...

We study the universe evolution starting from the sub-Planckian scale to present times. The requirement for an exponential expansion of the space with the observed metric as a final stage leads to significant restrictions ...
