Large-Scale Structure of the Universe and Cosmological Perturbation Theory
We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravitational instability, from the linear to the non-linear regime. This includes Eulerian and Lagrangian PT, non-linear approximations, and a brief description of numerical simulation techniques. We then cover the basic st...
متن کاملDivergence of Perturbation Theory and Resummation
Current determinations of fundamental constants [1] and the comparison of theory and expriment in high-precision experiments are based on perturbative expansions which can at best be regarded as divergent, asymptotic series in the coupling constant [2]. The first terms of the series decrease in absolute magnitude, before the factorial growth of the perturbative coefficients overcompensates the ...
متن کاملLarge-Scale Structures in Ilkhanid Architecture and Gothic Style of Europe
The mutual experience of European architecture during the transmission phase of Romanesque (around 11th and 12th centuries) to Gothic style simultaneous with Mongol invasions and political revolution from Seljuk empire to Ilkhanids have been assumed as a turning point through Iranian and European architecture. Thus, clarifying its mutual properties is one of the controversial discussion topics ...

متن کاملEvaluation of Close-Range Photogrammetric Technique for Deformation Monitoring of Large-Scale Structures: A review
Close-range photogrammetry has been used in many applications in recent decades in various fields such as industry, cultural heritage, medicine and civil engineering. As an important tool for displacement measurement and deformation monitoring, close-range photogrammetry has generally been employed in industrial plants, quality control and accidents. Although close-range photogrammetric applica...
