|Title:||About non standard Lagrangians in cosmology||Authors:||Dimitrijevic D.
|Issue Date:||1-Dec-2012||Journal:||AIP Conference Proceedings||Abstract:||A review of non standard Lagrangians present in modern cosmological models will be considered. Well known example of non standard Lagrangian is Dirac-Born-Infeld (DBI) type Lagrangian for tachyon field. Another type of non standard Lagrangian under consideration contains scalar field which describes open p-adic string tachyon and is called p-adic string theory Lagrangian. We will investigate homogenous cases of both DBI and p-adic fields and obtain Lagrangians of the standard type which have the same equations of motions as aforementioned non standard one. © 2012 American Institute of Physics.||URI:||https://open.ni.ac.rs/handle/123456789/5||ISBN:||9780735410794||ISSN:||0094243X||DOI:||10.1063/1.4748066|
