We present a careful analysis of non scale-invariant insocurvature perturbation produced in the power-law inflation. We first derive the exact form of the two-point function for a massless scalar field φ in a power-law background, a (t) ∝ t1+n (n

It is suggested to take the topological properties of compact riemannian surfaces more completely into account in the quantum geometry of strings. We use the fact that linear real bundles over any manifold M and spinorial structures on it are both cl

Homogeneous cosmological models of all Bianchi types with a general (nondiagonal) metric are considered near the singularity. The spaces are filled with an arbitrary sourceless six-component electromagnetic field (EMF) and a perfect fluid at rest. It

We use the Selberg trace formula to derive the expressions for determinants of Laplacians acting in real line bundles over a compact Riemann surface of genus p>1. Such determinants may be important in studying the structure of quantum geometry of str

Diffraction and wave packet evolution are considered in non-archimedean quantum mechanics. The special features typical for non-archimedean problems are elucidated. The norms of non-archimedean coordinates and time correspond to our usual notion of s

A grand unified theory is presented in which all dimensional constants (masses and Newton's gravitational constant) arise due to spontaneous symmetry breaking. The necessary smallness of the amplitude of adiabatic perturations results from the small

An action which is a non-archimedean, ( p -adic) analogue of the worldsheet action of string theory is proposed. Proceeding from this action tree N -point amplitudes are obtained and they are coincident with on-shell tree amplitudes of some non-local

The exponentially damped electric field is shown to produce particles with a thermal spectrum from vacuum if the residual action of the field on the particles produced may be neglected.
