This talk presents some progress achieved in collaboration with A.Linde and D.Linde towards understanding the true nature of the global spatial structure of the Universe as well as the most general stationary characteristics of its timedependent state with eternally growing total volume. In our opinion, the simplest and, simultaneously, the most general version of inflationary cosmology is the ...

The precision reached by the recent CMB measurements gives new insights into the shape of the primordial power spectra of the cosmological perturbations. In the context of inflationary cosmology, this implies that the CMB data are now sensitive to the form of the inflaton potential. Most of the current approaches devoted to the derivation of the inflationary primordial power spectra, or to the ...

I will discuss the development of inflationary theory and its present status, including recent progress in describing de Sitter space and inflationary universe in string theory. ∗Extended version of the talk at the Nobel Symposium “Cosmology & String Theory,” August 2003

In spite of its many successes, the standard big-bang theory has faced serious problems, namely, the horizon, flatness, and monopole problems. In the beginning of the 1980s, an epoch-making idea called the inflationary scenario was advocated to solve these cosmological puzzles [1,2]. Later it was recognized that the concept gives us not only a solution to such puzzles, but also to the origin of...

The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...
